🧼 Bacto-Surge Mini Foam Filter by HIKARI Review

I have them in every one of my Betta tanks. They are small but mighty. Love the corner pieces (so easy to hide. They don't take up space in my 7 gallon tanks). I have a cheap blue pump and it works great and the betta ignores it.

Easy setup, small enough for my 3 gallon beta tank. I put it in on Friday after cleaning the tank and on Monday the water was still clean. The only problem I had was that the bottom weight wasn't heavy enough so I took a rock from another plant ornament and glued it to the base and covered it with gravel to make it heavier. now it stays where it is. I definitely recommend it.

I had a cheap foam filter before I used it - I thought it was a small tank and what a difference. However, when I received this, I noticed that the foam was thicker and larger. When I put it in the tank I couldn't hear anything - I think the bubbles are smaller due to the denser foam. Some complain that it floats - just compress it with a pair of strings with a filter submerged in water and once the air is released it stays submerged.

This is my first sponge filter and I love the size of my 30 gallon aquarium as I can tuck it in a corner and the plants hide it from view. . I bought it mainly for ventilation as I still have the HOB filter, but it also has the benefit of improving the nitrogen cycle. I thought it would be the type with the diffuser already installed for a finer, quieter gush, but it had yet to be added. It took some modifications to the basket to fit the rock but it works great now and I know my entire tank…

I've always had mechanical HOB filters in previous installations. They certainly work, but they take up a lot of tank space, are noisy, and can get temperamental. I did some research on foam filters to use with an air pump and decided to try this approach when installing a Marineland 5 gallon portrait aquarium. In a nutshell. I wish I had done this a long time ago. Set up was very easy, the filtration is great and the sponge is easy to hide behind the hardscape. Combined with the Tetra Whisper…

This is the perfect size for my 6 gallon Betta aquarium. The angled design allows for a snug fit on the side without looking awkward like some cylindrical sponges. I hooked it up to the Aquarium Co-Op Nano Air Pump. Works very well, this sponge filter also works well with my air valve. I also had a Co-Op coarse nano sponge filter, but I hated its coarseness. I felt the water was still full of debris and not clear. However, this Hikari Bacto-Surge polishes the water much better as it is thinner…
