have just split from my girlfriend and am now returning the tank back to how it was i dont want her tank to crash or kill her fish so what should i watch for once i remove the nutrafin kit
Well, the plant growth will be slower and so the tank may get algae.
In terms of stats wise the tank should be fine. Gradually the pH will return to normal (to what it was before you added the CO2).
IS that what you were asking?
yeah i think so basically she already has enough to say so dont wanna take all my stuff and then have her say i ruined her tank or killed her fish bla bla
