AQUANEAT Aquarium Bio Sponge Filter Breeding Fry Betta Shrimp Nano Fish Tank (Large up to 60Gal)

I just set this up in my 1.8gal Beta tank the other day. So far it’s amazing! This little filter is everything and more, that I was looking for. As I said, I just set it up, so I’ll have to come back and let you know how it does on keeping the tank clean, and ease of cleaning the sponge filter. I have two more 3 piece sets in my cart, because I want to make sure that I always have this product (there are no replacement filters (and I don’t know how long each one will last), but at this price, I’ll just replace the entire thing when needed). I got the 3 piece for $8.88 and it comes with 3 complete sets.

Works well in a 60 and 90 gallon tank. Originally switched from a large waterfall filter to these sponge filters when the waterfall filter started getting too loud and having parts wear out from sucking up sand. Since these sponge filters don't have moving parts and uses air to filter, you don't have to worry about parts breaking, just squeeze out the sponges during water changes and occasionally take apart the plastic to clean off buildup with vinegar. Can also rinse the sponges out into other tanks to introduce microbes and waste to new systems. Recommend getting an adjustable air pump to control the level of bubbling. Works well with floating plants and water roots. The sponges started showing wear after about two years.

Hook an air tube in to these and you are good to go. I use these in addition to other filtration and they work great. Clean them occasionally and they keep the water very clean. The sponges are very rigid, I have cleaned my countless times and they still work great

I had run out of filters for my goldfish, Fred. I was using an aerator stone only in his 2-gallon bowl. Of course, that does not filter water, so poor Fred's water was becoming dirty quickly. I put this filter in yesterday afternoon, and this morning, that bowl was clean! Super pleased with this. So is Fred. ;/

Great working
