Review on 🧼 Bacto-Surge Mini Foam Filter by HIKARI by James Murphy

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 will benefit from it.
