Fish Crazy
Well, my mother-in-law has given me a second-hand Biolife 35 filter. It's working, has all the parts and the manual with it but nowhere can I find the size of aquarium this is suitable for! Any ideas? My tank is 3' long and currently I'm running a Fluval 1, a generic mini filter and a Fluval 2 -- temporarily! I'm hoping the new filter will replace the fluval as it is a bit knackered, but will that mean my tank is underfiltered?
