Re: surface scum
Sorry, can't agree with your experience. My 30g tank has virtually zero surface
agitation, using a canister filter, and I have no surface scum. The only time I did
have that problem was when a fish died in the tank and bacteria proliferated. I
don't know why others are having scum problems, but using a canister filter with no
agitation is not the cause.
