Had a bit of a set back, happen on Jan 7 I was pretty devastated when it happen. Came home from work and recognized a not so good smell. I had placed a small light in the sump to help me see when I am working and unfortunately it came loose and of course fell right into the water. The light is so small that it didn't pop the circuit breaker when I grabbed it out of the sump I could feel the voltage. I threw a big bag of carbon into the filter sock and did about 15 gallon water change and prepared 25 more gallons.
First pic shows the crash I cant believe that I let something so stupid happen. It was very sad to see these corals that I grew out from 1 inch frags over 4 years ago basically melt away and there wasn't anything I could do about it.
2nd pic is about 3 days later all the acros bleached and where starting to take on algae, so I removed what I thought I could save and started throwing the rest out. I threw one of those big carbon blocks that you get at petco into the sump. I had to do something about the smell the whole house smelled. Pocilapora has made it along with some zoanthids and my frogspawn.
Interesting my fish showed no sign of distress, then again I only have 4 fish in a 75 gallon tank.
Tank is looking pretty good today. I feel confident that the crash is over and the tank is back up and running. I added some clean up crew and a few new frags including a pretty sweet torch. I am converting the tank to LPS and I am going to try some chalices. I have started up a new 125 gallon build that has been running for about 2 months with no livestock though it does have a 30 gallon frag tank that has some fish and corals in it.
3rd pic is my fishroom.
I think removing every thing, adding a lot of carbon and doing water changes helped in not losing the entire tank. I think if I would have let the acros continue to rot the whole tank would have been wiped out.
