I’ve had my tank setup for around five months now and the filter system only been cleaned once. how often should it be clean? I have a Fluval 304 unit.I have a 40 gallon tank. I have… 1 shrimpgoby, 2 pajama cardinal, 2 percula clownfish, 1 cleaner shrimp, 1 red general starfish. All of my fishes diet are different, some eat pellet, flake, brine or meaty. I have my tank water change every six weeks by a prof. however I only had my filter system cleaned once. So again how often should I have my filter system cleaned so my fishes can stay healthy.
Also should i clean my tank more often?
I just had my filter system cleaned two days ago.
