Review on 🌀 Hikari Bacto-Surge High Density Foam Filter: Enhance Filtration Performance with Large Size by Nathan Kalivas

Works great, perfect for fighting fish or those who prefer slow currents. I am currently using this reservoir and everything is going well with this filter. High quality foam and easy installation. I had to weigh it down with stones. The base is weighted, but it wasn't enough to stop it from rising. He lay there for a few hours and then started swimming. However, it's okay. I would definitely buy it again and can only recommend it. In fact, I'll probably be buying another quarantine sponge filter soon and will definitely be using the Bacto-Surge again.
