    • This might just be the perfect canister
Style: Biomaster Thermo 250
I took a chance as these didn't have a lot of reviews or videos online. I am using this in a mixed reef tank and it could very well be the perfect canister for this situation. To start it is silent!. When I first turned it on there was a slight water trickle noise which completely went away after a few hours. I suspect it was still purging some air pockets during this time. But now it is completely silent - no hum, no water noise, nothing. The only way I know its running is to look at the return line and see the water moving out into the tank. The pre-filter area is awesome. Oase offers 30ppi, 45ppi, 60ppi and 45ppi carbon sponges for the pre-filter. Mine came with the 45ppi carbon sponges. I have changed these out to the finer 60ppi sponges which are equivalent to approx 250 micron filters. With the 60ppi sponges I rinse them thoroughly every week but the process of doing so is so simple and quick. The benefit is my water gets a polished look and the canister stays clean so I dont have to open and clean it very often. I run purigen in the canister so I do have to open it once a month or so to replace and when I do the inside is virtually detritus free. The flow is superb. Inside the canister I have 1/2L of Seachem matrix in the bottom basket, 1/2L of Seachem matrix in the next basket, an empty third basket, and 100ml of purigen in the top. I let the prefilter area handle all my mechanical filtration and try not to cram too much media in the filter to slow it down. With this setup I am pushing 208 gph up 32" to my tank. (measured via an inline digital meter). I connected the heater to my JBJ controller for the first week to verify the accuracy of temperature and it was spot on. It maintains my 48 Gallon tank at a consistent 79 degrees. ... show more

    • Constantly Purging Air
Style: Biomaster Thermo 600
This filter is constantly sucking in air and as a result is making purging air noise every 5 minutes. I’ve had numerous Eheim filters over 15 years in the aquarium hobby and none have had this problem. I should have stuck with an Eheim, only reason why I bought this was because of its integrated heater feature. If you look online and in this product reviews, this air purging is a known issue. I called customer support directly had they were clueless. ... show more

    • Look for something else. This is a bad design
Style: Biomaster Thermo 600
First off I bought all the Hype from Youtube and others as to how good this filter is. Its not ! Here are the reasons: 1. The Filter seal has a design flaw and leaks, as well as sucks air. 2. The heater also sucks in air. 3. The air purge plunger also leaks. Clearly there has been serious review manipulation by OASE on Youtube and other places. Please have to make money so if OASE is paying a Youtuber for a good review that's what they do. Don't buy into the Hype like i did. Search the actual Forums of various aquarium sites and all the problems are there. I should have done that first before buying. Lesson learned. ... show more

    • Best Canister Filter Ever!
Style: Biomaster Thermo 250
Review Image by Samuel A. Samuel A.
Review Image by Samuel A. Samuel A.
I LOVE IT! I've been using two of these Thermo 250's on my freshwater 55 gal, for 3 weeks+ now. The Thermo 250 cost a lil more than most canister filters, but has 2 great features that make it worth the extra price. 1: It comes with a built in heater which is great, because that's less clutter in your aquarium. 2: It has a pre-filter on the intake that can be pulled out and cleaned separately, so you don't have to always clean the whole canister, and you can keep that good bacteria growing in the main filter trays. 3: It comes with 4 trays to add media too. 4: It's super quiet, my 60 gal rated air pump is louder then both of my 250Ts combined, and the air pump really quiet. I have not had to do any maintenance in my first month of running and the water flow is still very strong in my heavily fish stocked/planted aquarium. I have to be honest though; I'm only using the coarse circular intake filter pads that came with it, because I upgraded just about everything else. I also added jardli glass water intake and glass water outtake for that kool less clutter look. This is because I did some serious research on the net and good ol youtube. After a long search on all types of aquarium filters ie.. hang on back, canister, sponge, under gravel and sup, I came across this Thermo 250 Canister from Oase. Now just about all if not every youtube video on it was from a none english speaking country. Then I seen this random video that said "pimpmyfilter". I clicked on it and some British guy named the "pondguru" was giving a demonstration on how to make the Thermo 600 model more efficient. After watching that video I was completely hooked/sold on his way of making the Thermo Canister filter more efficient. I didn't do the drilling though, cause it doesn't seem to be needed, the water flow is still very strong. With that being said I can't give an honest opinion on how good the filter media is that came with it like the meduim and fine pads and the ceramic balls. Because, I pimped out both of my Thermo 250s from start. I am using the original black fine pads for the prefilter, because they work the best for trapping muck and not letting it through to the main filter. No matter what type of filter you get whether it's this one or another model or brand, I highly highly recommend that you go on YouTube and type "pimpmy(filter name here)filter" ie pimpmyoasethermofilter, pimpmyfluvalfilter, pimpmywhateverfilter. I promise you that that will be the most helpful thing you ever did when it comes to searching for and aquarium filter. No-one on the internet that I've seen is doing anything remotely close to what that guy does to aquarium fliters. He didn't pay me or ask me to promote his channel. He'll probably never know that I'm promoting his work. I'm just giving him mad props because he deserves it. Watch and see, and I bet you'll come back looking for this review to say that it really helped you. ... show more

    • Excellent Filter
Style: Biomaster Thermo 600
Review Image by Harveyvicky2006 Harveyvicky2006
I have this filter running on my 65 gallon fresh water aquarium. It replaced a Fluval G6 filter I had for about one year. I was never able to get that filter to pump at 100%. I have this filter running through a chiller. The chiller sits on the opposite side of the tank and I still get a strong return into the tank. Set up was very simple as I used the hosing and all the fittings from the G6, and just replaced the filter. I am using a foam pad on the bottom tray, the next four trays have nodes in them, and the top tray has a foam pad in it. The water in the tank sparkles. I have only been running the filter for two days, but so far I am extremely happy the way it is running. I plugged the heater into my controller set to 74 degrees, the temp stays at 73.8. Can’t complain about that. The filter is running in the living room and is super quite. You have to look at the tank to see water movement to know it’s running. If your looking to replace your filter I would recommend this filter the Oase BioMaster Thermo 600. ... show more
