I am new to the planted tank world. I bought this filter for my 5.5 gallon betta/shrimp planted tank. I found that even on the lowest setting with a prefilter sponge, the current is still stronger than I am comfortable with. Also, Aquarium Co-op no longer carries the Fluval brand replacement sponge (as far as I can tell). I wanted to replace my carbon pack with a second identical filter sponge and was not able to do this via Aquarium Co-op online. I ended up ordering a sponge filter and I am going to test it out and decide which one I prefer. The current is too strong for my betta and for my plants. I am going to save the AC20 for when I get a larger tank. And a side note, this does make some noise if any tiny thing gets into the impeller area so I do recommend a prefilter sponge and if it is loud, clean the impeller compartment and give it a few days to settle.
Overall I would buy again but not for a tank under 10 gallons.
Works perfectly, love the large are for boi rings etc. First order with Aquarium Co Op and I couldn’t be more satisfied. They will certainly be getting my business in the future 5 stars!
I had previously had a sponge filter running in my 5 gallon tank. I am using a fine gravel and found it to be dusty. As soon as I set up this filter it really helped create a nice adjustable current and clear water.
I would have given this filter 5 stars if it was more quiet.... it vibrates a little more than I'd like. It seems to be getting louder. Trying to figure out what to do to buffer or remedy this.
Overall an awesome filter with great options to customize to your specific needs.
Have two of these now the 20 and 50 works awesome.. shipping was great
This is the first HOB filter I've purchased. To this point, I've used whatever filter came with the "all-in-one basic aquarium kits" for my 5 gallon and 10 gallon tanks. But I decided the flow for my 10 gallon Guppy tank wasn't sufficient . . . so I upgraded to this filter. I also added the Aqarium CoOp Medium Pre Filter sponge (which is actually too large for this filter). So far so good! The flow is much better. I stuffed the media slot with a sponge filter, the bioring bag and the old sponge/filter floss bag I had in my previous filter, and it seems to be working well! Thumbs up for this filter in my 10 gal!
