| || | Air Filter in 10 Gal Tank
I have a 10 galleon tank that currently houses 2 cory catfish and 1 guppy and 1 platy and I have had this tank since July 2008. The tank has cycled and I check weekly to make sure the ammonia, nitrate and nitrites are good (low to nil). My biggest challenge is the pH level. I live in an area with extreme hard water and have been told by the fish stores that it's okay, that the fish adapt and the less chemicals one uses the better, which I agree with. The only thing I add is a water conditioner.
Now having said that, my 10 galleon tank has a heater and a filter, but I'm wondering if I should also have an air filter, is this vital for tanks, can fish die without one? The reason I ask this is I have lost a guppy and for the life of me I can't figure out why, everything points to being fine, so for him to die seemed strange, so I was wondering if oxygen starvation may be a potential cause?
Any suggestions would be appreciated.
