When should I change my filter cartridges(not the whole damn filter)but the thing that collects dirt and whatnot. Every week my filter cartridges turn dark brown everywhere. Also my fish tank water get a little blurry and the water smells odorless.
I have 4 goldfish.
When should I also change my tank 100% I usually do 100% changes every week.
My fishtank is 20 gallons and it's big enough for my four little goldfishies.
I feed my goldfishies like 2 little pellets every 8 hours.
I do use those water conditioners
filter is 20 gallon power
