I don't know beacuse I got my water tested by this shop (LFS
) And I trust them, beacuse they have very healthy fish there.. My fish is al better now! I turned the filter on.. But it was stuff on the filter!! I thought it was dead, but then i shook the filter and it started swimming again. Thanks for the concern though. Hows your pale clown fish..? Hope it's doing better. I read about it that it spreads and its a diseas that's common among clown fishes!! Well good luuuck!!
