I am worried about my nano being unstable after it crashed (so to speak) last week. My pH is back up to a good 8-2 and holding. The other parameters are: calcium 430, carbonate hardness 11, ammonia -0-, nitrite -0-, nitrates less than 10, phosphate is -0-.
How long should I wait to start repopulating corals? I am thinking a week to 2 weeks?

If all the perams are fine, fish are fine and eating, you could start adding corals now if you wanted.
Just when you add corals, dont add the water from the bag they came in to the tank.
It may pay to do a water change the next day if they release anything during the transfer.

Thank you, I will be able to start on Sat putting stuff in. Since I have "store credit' on the corals I can go back and get some more.
