I have 2 20 gallon tanks what size do I get
- I have a 40 gallon acrylic freshwater tank. I have to replace the large filter once a week. I have another smaller glass tank ( 10 gallon) and I use the smaller filter. This tank is too small for the number of fish I have in it. My plecto got too big for this tank. I'm looking for a 100 gallon tank so I can consolidate everything and only clean one tank.

Will this work on the quiet flow 40 internal filter? It is not listed on box
- Yes it should fit
Helpful?
How soon can I change aquarium fish water after adding new filter cartridge?
- If I'm not mistaken, rinsing your filter media under tap water is not recommended because of chlorine. I've always been told to rinse your filter in tank water. Is it as effective as running water? No, but you won't risk killing off the beneficial bacteria with chlorinated water.
