no.. it wont kill the biofilter if the biofilter is established... like at least a
couple months old. it will knock off a couple layers on top of the colonies but they
will pick right up. .same with the algae. I have not even seen an ammonia spike..
altho I am usually somewhat under stocked. best is not feed day before and day after
if worried about ammonia spike. yeah. turn off the biofilter OR, move it to tub of
water for the day if that is easy to do. a cannister filter will need to be flushed
before restarting into teh tank cause there can be anaerobic breakdown products
inside there. filters often contain a lot of organic material that eat up the PP.
on ponds filters really gotta be stopped. however, under no circumstances stop the
aeration. Ingrid

One of my Goldfish has a white bump on his nose and it's getting bigger. It
doesn't seem to have them anywhere else on it's body and none of the other
fish seem affected. I think it's fungus, but I'm not sure. I was going to
treat the tank with PP, as it's a pain to move him because of his size. So I
was wondering if the PP dose at 2 PPM will kill my biofilter? I was
considering turning off one of the filters for an hour (max) until the PP
had diminished somewhat and then restarting it before the bacteria died of
oxygen starvation.
