Features

  • Ventilation slots in the lid of the filter and aeration grooves in the outflow ensure that water returned to the tank is fully oxygenated and maximize gas exchange during filtration.
  • The pump pushes water up into the basket of the filter, entering through the bottom of the basket and being pushed out the top. A bottom-to-top flow ensures that water comes into contact will all filter media, and cannot go around or over filter media as with hang on back filters with a back-to-front flow.
  • The pump is also insulated and silent, making it excellent for office or dining room aquariums, and has extremely low power consumption for the amount of output.
  • The basket is designed with raised slots which catch detritus rather than allowing it to fall through back into the filter when flow is stopped.
  • A heater can be attached to the side with an optional heater clip, allowing for better dispersal of heated water through the aquarium.

    • Worthy successor to the 'King' of HOB's, with minor quirks.
About a year ago I re-entered the aquarium hobby after being "dry" for 15 years. And I've been looking for a powered filter to use on my 125 gallon aquarium. I have been using ATI sponge filters, which are superb biological filters, however, they're poor mechanical filters and have no chemical filtration ability whatsoever. In the past I have used AquaClears and Fluval canisters, and I seriously considered a canister filter, but there seems to be too much hit and miss in QC and after going through two canister returns with amazon, I decided to go with a simple HOB. I narrowed my choices to the tried and true AC110 and the newcomer, SC Tidal 110 to compare side by side. The Tidal overall looks and feels like quality. The plastic is durable with some flexibility, like stiff Rubbermaid material. And I really like the internal basket design, its very easy to lift out of the filter while holding the contents, and the filter top cover doubles as a tray for holding the internal basket so it keeps water spill to a minimum, very cool idea. The AC plastic is chintzy and has cheapened further since I last used them. It appears very fragile and parts came broken in the box, though still functional. The basket takes a little effort to pop loose, it seems they've added tabs to keep it in place. The Tidal also has a slot tab you can use to lock the basket down. Slide it out and the basket comes out easily. After washing everything out with tap water and placing it on my tank and plugging it in, it self primed within a couple seconds and began splashing water out immediately. Very impressive start. Except it was noisy at the beginning; it produces a very audible whirring sound. However, the pump sound can be greatly minimized by bringing the water level up until it reaches the spillway, or about 1/4" from the top of the surface skimmer slits. Reducing the flow also makes the pump significantly quieter. The self priming feature is also nice during water changes, I can unplug my filters, water remains inside the HOB, it does not drain out, and begins output immediately after being plugged back in. The AC had to be filled with water first, not a big deal, it fully primed after about 10 seconds. The AC is a little louder than the Tidal, a different type of noise, more of a rattling vibration, however it cant really be reduced. And the AC doesn't always prime back up from a power failure. Although this can be mitigated by using a small cheap office UPS to plug the filter into, which I already use. The Tidal outputs a lot of water and the spillway is designed to reduce splashing sounds, which works fairly well as long as the water level is high enough. If the water level is too low, it will actually be louder than the AC at equal water level. I would keep the water level 1/4 below the top of the surface skimmer slits on the Tidal for the pump and splashing noise reduction. The minimum water level recommendation line on the filter itself is much too low for quite operation. The tidal has excellent media capacity. It comes with a small coarse sponge for mechanical filtration, although there is a good reason for that (you'll see later on design issues) and comes with a media bag filled with 500 grams of Seachem Matrix. There is definitely room to double the media capacity, which I have done. The AC media compartment, while it looks huge, is probably about equal or possibly less; with a large sponge block, bag of bio rings (390 gram bag) and carbon pack (255 grams), it looks near capacity. One of the things I like the most about the Tidal is that there are NO O-rings to worry about leaking. Aside from somehow puncturing or cracking the filter housing, you have virtually no risk of leaks. The pump is housed inside the part that sits in the aquarium, everything hanging off the back of the aquarium is one piece of formed plastic. The pump can easily be replaced; I love that from a maintenance/emergency replacement scenario perspective. And the tidal 110 pump is cheap enough to keep a spare handy ($23ish.) The AC pump twists into the back end of the HOB, sealed with with an O-Ring; it can leak if you don't use pure silicone grease when re-installing the pump. Contrary to popular advice, never use petroleum jelly or Vaseline on filter o-rings, it will only harden the rings over time. Pure food grade silicone grease, such as used for diving should be used Trident Silicone Grease 1/4 oz. Jar . And a new AC pump costs almost as much as a new AC filter, not as cheap to have a spare. Other tidbits; the heater clip is a nice touch and the leveling screw is a new level of refinement for an HOB. The leveling device on the AC is primitive by comparison, but functional. While the Tidal is a very good filter, there are some things to point out which may or may not be issues for you... The Tidal actually has three levels of intake; the intake strainer (low water column), slits beneath the pump housing (mid water column) and the surface skimmer (surface water). Closing the intake tube is supposed to improve skimming performance, although I cant tell for sure its doing much. Leaving it open divides the intake 3 ways, leaving the intake strainer with the least amount of suction of the three. The suction on the intake strainer is so weak, that sometimes small particles of detritus can float by without being pulled up. This would make using a pre-filter useless, or at least unnecessary. The plus side is if you have fine gravel or sand, you don't ever have to worry about it being pulled in and wearing down your pump. And I do like the friction click telescoping of the intake, it feels very solid and well thought out. Even if its suction is the weak, its still pulling in water from the lowest column. I keep mine fully extended and in a 125 gallon aquarium, its about 6-7" from the bottom. The other thing to keep in mind is bypass, all filters have this to some degree, however the tidal is unique in that it is designed to let you know when this is occurring. The Tidal design channels water from beneath and up through the media basket (and it does a very good job of this), however, adding a finer sponge or filter floss will cause bypass after a few days once clogged with detritus. The tidal lets you know this by floating the little maintenance alert indicator on the lid. When this is up, it basically means that water is beginning to flow around the basket, and into the channel where the float rests. Personally, I like the fact that the filter is designed this way so that I know exactly when bypass is occurring. And after carefully observing the filter during a maintenance alert, it seems that much of the water is still upwelling through the basket, but some of it is also going around, as water will always flow through least resistance. Its not a total bypass. However, by supplying only a small coarse sponge for mechanical filtration, it seems that Seachem knows that bypass will occur sooner if a finer sponge is used. I currently have two Tidal 110's running and have different media configurations in each. From bottom to top, one has two tidal 110 sponges and 500 grams of fluval biomax mixed in the bag with the supplied 500 grams of matrix. No maintenance alert in over two weeks. The other tidal has a single 110 sponge, about 4 inches of Fairfield the Original Poly-Fil Premium 100% Polyester Fiber Fill Bag, 20 Ounces, White and the media bag with 500g biomax/500g matrix. After about 3 days, the maintenance alert pops up fully and the poly-fil is absolutely filthy. I can extend maintenance to a week by reducing the flow and the indicator drops, reducing bypass to zero. With two Tidal 110's running on my 125g aquarium, there is almost no detritus on the gravel during maintenance (compared to when I only had sponge filters, it was a field of fish waste) the circulation of the output does a very good job of keeping all solids suspended in the water column until it gets suctioned into the filter. I have to turn the pump all the way low on both units before feeding, otherwise the food gets circulated all throughout the aquarium. And maintenance on this filter is very easy and simple; pull the media basket up, let it drain, place it on the lid, rinse media bag in a bucket of aquarium water, rinse sponges and replace poly-fil. Because its so easy to maintain, I don't mind doing it with every weekly water change. Other filters, such as canisters require more commitment in time and are messy by far in comparison. I'm very impressed with the Tidal, a lot of good ideas went into the design of the filter and overall I think it has more pros than cons. Opinions on the internet seem divided on this filter, however, after scrutinizing its functions and playing with different media stacking configurations, I have to say it is a very well thought out design, I would dare say the best powered filter available to date. If you're not using a sump, use this. At the time of this review I paid $59 for the Tidal 110 and $79 for the AC110. On price alone the Tidal beats the AC handily. And the Tidal is a much higher quality product overall. ... show more

    • Best HOB filter period! As expected after reading many reviews elsewhere in this filter.
The filter performs exactly as expected. There are a lot of YouTube reviews talking about the water bypass of the internal basket. This is mostly true. You can not stuff this thing full of polyfil or fine sponge like filtration. I didn’t use the factory very corse sponge as I run a medium to corse prefilter on my filters. Instead I placed a medium density pad in the bottom in place of the factory foam using it as a template. I then place a fine layer of polyfil on top then cramed as much matrix and pond matrix (as it’s what I had been running in another filter in same tank and was already seeded with bacteria otherwise I’d have filled with just regular matrix media) I got roughly 1.5k of pond matrix and 1.5k of matrix stuffed in there. And I do mean stuffed as the top of the filter bags are slightly above the water level in the filter. When you set this up you need to play around with a few different setups at first to find a happy medium. If you pack the filter full or use a lot of fine filtering sponge you will not be able to run the flow at max as the water will backup around the basket then flow over the back of it creating bypass. What I’ve done is leave the lid off and slowly dial the flow up until I can see the water between the basket and filter housing about to bypass. I then back it down just a smidge to allow for clogging of sponges and slower flow as a result wo getting bypass. I then place the lid on top. Upon doing this I noticed the cleaning needed indicator that pops up from the lid is a great tool in determining the proper flow for media setup. Bypass occurs right around the point where the pop up indicator is flush with the lid. (Normal position is recessed and lots of bypass it’s sticking above the lid) I’ve placed this on a heavily planted 44g corner hex with some angles and dwarf guramis and a couple dwarf yellow labs. The filter has more then enough flow to upset my angles before reaching bypass. I’ll admit I do run a little more flow then most with angles as being heavily planted I want to insure good circulation for plant fertilization. I estimate I’m running this 110 filter at around 60-75% of maximim flow rate which is just enough to sway the plants in this 30” deep tank. I’m not sure if this filter is capable of filtering anything more then a 75g tank max. You would have to be very lienant in your mechanicle filtration setup to achieve enough flow wo having any bypass. I would still put this above the aqua clear filters though for several reasons. By design all aqua leads have lots of bypass that you can not get rid of as the water enters the basket in the middle not the bottom like the tidals. I will say the aquaclears are a little quieter. They make more water splash noise but the motor on the tidals emits a slight hum similar to most canister filters. It’s not loud but enough my daughter complains about it being in her bedroom. I wouldn’t hesitate to put it in any main room but bedrooms might not be suited. If you run your waterline up to the bottom of the water outlet it leaves just enough for the skinner to work correctly and I find this a very well thought out design. Speaking of the skimming function I did find it annoying that you can’t turn the skimmer off however I found the flow of the water outlet vs the suction of the skinner when the underwater suction is max prevents feeding issues. I just simply feed the fish on the outlet side of the filter instead of the inlet side. The flow keeps the food moving and doesn’t get sucked into the inlets this way. Not a big deal at all just drop the food in a different place and problem solved wo even turning down the filter at all. Bottom line this filter design is hands down the best hob design on the market. You might not be able to achieve the flow you want but you will get much better filtration then any other competitor cause you can actually see the water bypass and the flow adjustment knob allows you to dial it back and prevent this which no other filter on the market can. I would strongly suggest using a prefilter sponge in the intake to achieve maximum mechanical filtration but at same time I would recommend the same to anyone getting any filter period. I’m not even a hob fan tbh I run canisters on pretty much anything over 20g. With that said I’m severely reconsidering my bias after using this filter cause the adjustability vs the media capacity vs the extra water polishing you get from any hob over a canister filter is simply amazing. If I were to run this with the factory sponge I have no doubt I could get enough flow for a very large tank... but that said I prefer water dwell time over turnover rates as it’s much more important. Being able to physically see the bypass point and adjust is well worth the sacrifice in flow. Update. I have found a setup that will allow full flow wo bypass. Prefilter is still in place but I placed the factory corse sponge in place of my medium pond foam stuffed a fairly thick level of poly in then both media bags and then filled any gaps around the bags with more poly. I’m at about 1l matrix and 1l if pond matrix now and all media is submerged properly and I am able to run this wide open if I want. I might later remove the basket foam entirely and just use poly but I’ve noticed the skimmer and the other intakes under the filter and in the sides tend to suck up a lot of stuff going wo a foam in the basket might require weekly changing of polyfil. I’m thinking I might just cover the skimmer and other intakes with black leggings remove my prefilter sponge and cover it with the same and then just run a thin fine pad and Purigen in the basket under the media bags. ... show more

    • Best filter ever!
There are so many videos on YouTube showing this product and how to use/modify. What attracted me the most was the size of the media holding tank, motor is in the water, adjustable flow, adjustable surface skimming, and adjustable down tube. My filter was noiser than expected when it was new. It has since settled in and much quieter. Absolutely recommend watching some videos then buying this fantastic filter! ... show more

    • Quality, self-priming HOB, but HATE the surface skimmer
I've had this filter for over a year in a 95 gallon planted community tank, and overall it's been very good. It filters well and runs quietly most of the time. The self-priming feature is essential in my opinion as it starts right up after power outages and keeps it quiet. I like the media basket--it's roomy and cleaning is easy. At first I didn't think the surface skimmer was a big deal. I put a piece of thin foam over it to keep out fry/debris and it was usually fine. However, any time that a plant leaf gets stuck on it, it starts to make horrendously loud sucking noises. Right now, my water level is 1/4 inch below the black rim, and that is also too low for the skimmer--it sucks air and is SUPER loud and obnoxious. There needs to be an update to this filter to include a feature that shuts off the surface skimmer so that people with shrimp/fry/small fish/snails and plants can run this more effectively without the issues of things getting sucked up by the surface skimmer inlet. It's easy to pop a pre-filter sponge on the main intake, but the surface skimmer is a big deficit at least in my application. ... show more
