I’ve never used or thought about using a sponge filter for my tank. That’s until I started watching Cory’s videos about how great sponge filters are and boy was he right. I bought mine about a months ago and my tank has never been this clear even with a few gold fish. Now I’m ordering the small sponge filter for my beta tank. Extremely satisfied, highly recommend this product. ( I also have the large intake sponge in the hang on back)
I love it. So quite.
In my opinion this is one of the best sponge filters available. It helps to polish the water as it is a finer pore material but also gives good beneficial bacteria growth. I am using this specific filter in numerous of my tanks. And a big plus for breeding fish is I often see fry picking off the sponge.
I used to have such a hard time with HOB filters but thanks to Cory and his awesome educational videos, I now love sponge filters. They are easier for the newer fish hobbyist to maintain. They are also weighted and really contributes to crystal clear water!
I have several of these. I'm breeding guppies and a very high success rate for fry. I have a few that are modified with K1 micro. Combine that with plants and I go 3 weeks between water changes with sensitive fry. It's easy and effective. Only down side is looks. But you will have happy healthy fish.
