ok i got a few test kits.
strips and this master one i place in the tank.
it was a light green on the strip..i think safe or something above(bad)
and then after adding prime to the tank it turned yellow safe on the master board.
how long does it take for fish to get used to the tank and start eating?
when will they come up to the top to eat?
also i read that ID sharks have bad eye sight but are they like blind? can they not see the flakes above(which the former owner grew them to 6") i mean if not, they should smell it right?
