Temp 77
Ammonia 0
Nitrite 0
Nitrate 20
SG 35
pH 8.1
Alk 8
Phosphate 0
Ca 500
Mg 1470

Is the Nitrate still too high to had a fish and coral? I am going to do a 20% WC in a little while so that you knock it down a bit.

Once you do your water change you should be good with the Nitrate. I would lower Calcium and Magnesium though by not dosing until levels are in the acceptable range. Happy Reefing!

That was my next question. So far I haven't dosed anything but I plan on Kalk, so I suppose I should have that ready when the time comes so that I don't have to purchased supplements to bring the levels back up.

I think I need to get the Alk up and the Ca down before I start adding kalk. How do I lower Mg iirc there is a relationship between having Mg at the correct level and being able to maintain Ca at the correct level or was it Alk.

Nitrate at the level is safe for fish and probably most corals. I'd wait for a week of zero ammonia, do a few water changes, and work from there. The week of zero ammonia will give some time to make sure that the decay is over and that there isn't going to be a second ammonia spike. Secondary ammonia spikes seem to be rare, but they can happen. My guess is that they can be caused by something large in the live rock dying, but that's only a guess.

Thanks, Jon you are always a go to source.
