Chance of recovering from this crash? Would like some input if you have the time.

Well It has finally happened to me as well. The long and short of it is this, I recently hooked up a kalk reactor in line with my auto top off system. And let's just say it raised my pH a a tad.... to I would say in the ballpark of 10, and this all happened when I was out to work for the day. And to add insult to injury my pH meter is busted to I had to scramble to find I replacement which I did 5 hours later.

Well I now have the pH back down into the normal range, and have pulled the kalk reactor out of line. As a result of even most of my corals are suffering greatly (on the bright side, my fish, shimp, clams, snails, and hermits appear to be doing just fine).

As for the corals this caused a massive bleaching event. Causing the water to have a brown/green tint to it from the amount of zooxanthellae that is now present in the water column. I have been skimming around the clock to try and remove as much of this as I can and clear up the water, and the skimmer is doing a good job of pulling it out.

From what i have read some times it is hard to tell the difference between a coral bleaching and actual tissue recession. Most of the corals still have polyps present, though they are retracted (some are even showing signs of extention again).

I am just looking for people input and seeing if they have ever had a similar event take place. What was the out come? Any advice on how to continue helping the tank recover?

Thanks.
 
I had the same thing happen to me a few years ago, i did loose some corals but over all the tank recovered nicely in a short time. As long as the corals still have theri polyps then there is no tissue lost and no sign of RTN they will recover.
 
Very surprised you didnt have a massive snow shower. I actually had a bran new batch of Randy's DIY 2 part (1 gallon each of ca/alk) dump into my 75g tank within 30 mins while I was out getting something to eat. Needless to say it was pure milk in there and after a massive water change a few hours later, I didnt lose even one coral.....
 
Horace.... I know what you mean about the snow shower. From what I have read when the pH gets that high stuff comes crashing out of solution. But for some reason it didn't. I thought it was kinda weird but in all the confusion, I didn't pay it much mind.

Amphiprion: Yeah I know it is not really a crash, but it sure felt like one.

I guess I will have to just wait and see if there was tissue loss of not. It is still kinda tough to tell. I might have to frag off a couple of my milli's it looked like tissue was starting to pull a way on those. I hope they are still in a condition to do so when I get home.
 
Believe it or not I think its actually better if you get a snow storm because when that occurs the chemical reaction caused by the precipitation brings your PH back down until the reaction stops.
 
Happened to me a year ago, I lost some of the more hard to keep acroporas, and had to dose vinegar to get the ph down. The monti's were unaffected, some acros still lived, but some got burned and died, I lost some fish too a wrasse and a fairly basslet, but the blue tang and rabbitfish survived...also the coral banded shrimp..

Lots of water changes... carbon, vinegar and time... Good luck.
 
ahhh. don't feel bad. It was my fault. Wasn't being careful. I have some ideas for how not to repeat what happened. On the bright side, I get to get new corals.

I guess one question I have is, is it possible to have tissue lose but still have polyps in effected areas?

You can but the polyps don't last long(hours). Sounds like your cporals didn't loose tissue but in fact bleached. Sorry to hear about your troubles. Some TLC and time will hopefully see most recover.

Just to update. A number of colonies did in fact loose their tissue. I was able to save parts of some of them, but for others there wan't much hope. I will probably get the reactor back up and running when i can spend some time at home and monitor the pH through out the day to make sure that too much kalk isn't being added. I will probably T of my topoff water line so that one line goes straight to the tank. then the other line will be on a valve, that goes to the reactor and then to the tank. This why I and dial up or down the amount of kalk that is being added, and get a stable pH.
