Reef Central Online Community - View Single Post - HELP - Float switch failed, topped-off lots of kalk

rsuplido · 03/18/2009, 04:58 PM

My float switch failed on my 30g and my kalk top-off kept pouring. 2 hours have passed when I noticed it. PH shot up to 9.2. After 2 hours, PH started going down since my 3g reservoir was empty (I estimate about 1.5 to 2g of kalk got to the tank).

I started bubbling CO2 slowly in the sump until PH got back down to about 8.5.

What's next? I'm afraid to test for Alk and Cal since I know they will be off the charts. Should I do a 15, 30, 50 percent water change? While the fishes look fine, I'm afraid I would continue shocking the SPS if I do a big water change.

Some advice please.
