What size for 20 gallon
Answer by Emma • Oct 01, 2021
It gives you a size chart, but:
The small one is sufficient for a 20 gallon tank. It's actually pretty big. I use mine along with my HOB filter to make the water extra sparkling clean.
is this filter a one month use and clean and reuse ..How many times? or discard monthly.
Answer by • Feb 19, 2019
For optimum performance, replace the sponge block every six months. Allow the new block to soak in your aquarium water for a minimum of two weeks before installation to allow it to colonize with nitrifying bacteria.
Why do I need to replace it every six months for optimum performance? I mean it is meant for the beneficial bacteria to colonize so shouldn’t you be able to use it for as long as the sponge is still in good condition after rinsing it with aquarium water each month?
