Is it milky cloudy? Sounds like a bacteria bloom, which means you tank might be getting close to the second stage of cycling (so to speak). Bad part is the ammo lock might be keeping the ammo in check sans regular PWC
, but when the nitrItes (no2
) hit, it won't protect you fish from it. I'd suggest getting a liquid test kit (ie API FW
Master test kit) and doing regular 50% PWC
(partial water changes).
Here's a link that'll help you along: I just learned about cycling but I already have fish. What now?!
