Thank you maya.
I'd rather not risk anything in the future so I might as well get the new rocks and sand now. lesson learned.. the hard way.
I spent all day preparing 2 10 gallon tanks (among other things). I'm thinking of putting 2 clowns in one and 3 green chromis in the other until my main tank recycles.
Can they last in there that long? I mean, won't those tanks cycle too? Easier to do PWC
's though I guess.
