This is a great little filter for my betta. He is very picky about current and this filter finally did the trick. The adjustable flow is awesome to have on such a small filter. Very quiet and easy to set up. Mine originally got damaged in shipping and I was immediately sent a new one without any hassle. Great filter and great customer service.
I'm setting up 4 tanks for my new Bettas. I had watched Corey's video on filter hacks and was very impressed with his system. With needing 4 new filters economy was foremost in the planning. I purchased the filters, AquaClear foam inserts and the Filter-Max IIi Pre-filters. They were so easy to set up, only took a few minutes, plugged them in and after the initial priming noise settled, they are as can be. I would highly recommend this system.
This filter is so great and I modified it even though it didn't need to.very low maintenance (5 stars)
I used this to replace the filter that came with my 2.5 gallon nano bow tank. This filter is a huge upgrade! It's Very Quiet! Plus it's pretty powerful for it's size, yet you can adjust the flow, a very useful feature. Thanks to Corey and Aquarium Co-op for a great little workhorse filter!
I didn't know anything about this filter going in and just took a flyer on it. It has been pretty solid and is easily modifiable.
