BTA not so hot

[belzebuth]

The pump/overflow and skimmer were still running hooked onto my next door neighbor hydro. The red sea wavemaker was unplugged for about 5 hours, so I had no powerheads running.

I don't know what could of happend? Nothing changed. I did not add anything to the tank. All we did is upgrade the main service on the house and add a sub panel in the fish room. The fish seemed a little freak out when everything was turned back on... I will test all water parameters when I get home. Beside the BTA not looking hot, My Anthelia is not looking good and the GSP are not extending their polyps. Everything else look fine.

I am also making salt water, getting ready for a water change.
