I bought this to go in conjunction with the existing filters I have. at the same time I purchase the fertilizer package. I have been battling brow algae for a while before getting this stuff, the brown algae is almost gone now. Highly recommend this
I added it to my 30 Gallon tank to work in tandem with my HOB. Goldfish are slobs, and the HOB, while it filters up to 300 Gallons per hour I didn't feel was enough for my two water pigs. Added one of these to my tank, and I love them working together. My fish love it because duckweed and other food gets stuck to it and they pick it off all day long. Even my bristlenose loves it. He has turned the underside of it into an impromptu cave of sorts (even though there are three caves in the tank).
great product, i recommended
I like the fact that it is well weighted. My shrimp love hiding under it. It works well. It would have been nice if the package and/or website had said "no air stone needed". Thought I needed one but I don't, kinda wasted $ buying a stone for it.
Items arrived within just a few days. The sponge filter is awesome! Had to tweak it a bit with needle nose pliers to make the airstone fit, but love the peace and quiet over the hang on backs. Thanks so much!
I put 1 in my 20 gallon planted beta tank and 1 in my 29 gallon floating plant community tank (assorted barbs). After a few weeks I removed my hobs and never looked back! Freed up 3 outlets (sharing air pump). They run so quiet and I love the crystal clear water and easy maintenance.
Works great for my 60gal aquarium. I bought 2.
I am using this in addition to a canister filter in one of my tanks and it does a great job at giving extra flow in the tank and making the water extra clear. Material looks durable, affordable and is easy to use. Great option if you want filtration that is consistently reliable, will almost never fail, and is useful for lots of things like setting up quarantine tanks, filtering tanks during power outages, putting beneficial bacteria in a new tank, and keeping shrimp or fry safe. A good cheap investment for any fish keeper and will definitely be useful for everyone at some point in the future.
I've recently switched to sponge filters from canister filters. I bought 1 Hikari and 1 hydro sponge filter from aquarium coop for my 125 and I love both of them. My water is as clear as its ever been. I will be using sponge filters in all of my tanks from now on!!!
I recently set up a small fishroom. (20 tanks) and using these to filter all my tanks. Very cost effective and added security when paired with aquarium co-op check valves. This product is a must for any avid fishkeeper.
I'm running this and a large coarse sponge filter in a 40 breeder and they work great, i like how quiet they are compared to a hob and i can put my tank tight against the wall. and maintenance is very easy.
I have this set up and running in my 40G tank in addition to another sponge filter, my tank is looking nice and clear now.
The sponge, plastic parts, and weighted bottom all look and feel like quality. Highly recommended
Great large filter. It claims up to 75 Gallons, I'm using it in a 40 Breeder. Very Quiet!! I love it!
