UPDATE EDIT- It's been about 4 months now, and it's still working great. It's very easy to clean. You can just unlock/twist the compartments from the suctioned white top during a water change, and pull them out. Rinse them in the siphoned water, then reattach them. Also, don't forget to unplug it when changing the water. There are tetras and even smaller emerald rasboras in this tank, and no one has been sucked/stuck. This filter is probably moving more water than the aquaclear 50 hob on the other side of the tank. A piece of flake food can travel a full clockwise circle in this tall tank. I've just kept the sponges in there most of the time, but it was blessedly easy to switch out media when I did. Easier than I've experienced with other filters. So far, this filter has provided the best value for money I've spent on aquarium equipment. Thank you Fishkeeper. This filter might be too powerful for a tank with delicate animals like shrimp or seahorses or for tanks 15 gallons or less. Just love this filter! Powerful, versatile and easy to clean. I have a sand substrate, so I wanted a filter where the impellar would be relatively safe from potential sand particles (petco black sand + seachem black sand). The impellar is on top, and particulates have to travel through up to 3 sponges before possibly hitting it. I've been running this filter a little over a month with no problem. I used just two of the compartments for a few weeks and recently added the third. There are lava rocks underneath the intake tube just to put some barrier between it and the sand. It's easy to change the sponges out with different media. The sponges themselves have removable center inserts. Very easy to clean, and debris doesn't go all over the place when you unplug it like some other internal filters. And you can adjust oxygen flow! A simple design and very effective. There's plenty of crap out there, but this is great! So thankful because I've wasted money on said crap in the past. This does exactly what it says, and the price is great. This tank is a topfin 37 gallons. ... show more

    • Works for bigger fish
Size: 8W for 40~70 gallon tanks
I have a community fish tank that has fish that’s size ranges from a large Molly to small breeds of guppies. Sadly a few of my smaller guppies and endlers got sucked up and killed due to the large intake wholes even with the fish guard. So I don’t recommend if you have smaller fish. I Transferred my smaller fish into a tank of their own and haven’t had any issues other than that sense. ... show more

    • Great filter for my red eared slider baby. Born this spring.
Size: 8W for 40~70 gallon tanks
Great filter easy to use, very versatile, filters well. You can have no bubbles little bubbles or a lot of bubbles. Slow swimming turtles need room as it puts out a lot of water. My turtle loves the fast water, it’s an amazing swimmer. The only drawback i’ve found is that it doesn’t do well on sand. Sit it on rocks or above ground level. Small fish can be sucked in at the bottom so make sure the little screen is in place at the bottom ... show more

I've read reviews on this filter. people said it helps to clean water. It has not helped with my yet. I've had it in my fish tank for 11 days still green water. It looked like it was getting better then went back green. I've never had an issue with green water before. I do feel it adds oxygen in the fish tank. I've done two water changes since I've added this filter to my tank. It looks better then it did. Hopefully it's on the right track. After this filter ran for 11 days still with green water. I did almost 50% water change two days in roll It went from green to cloudy. Then cleared up after a few days. I'm not saying for everyone to do what I did. Because doing big amounts of water change several days in a row can stress your fish. Within the first 11 days you could tell the sponges was getting dirty. They had brown on them. Now that my tank has cleared up, the sponges doesn't get nearly that dirty. ... show more
