Hey guys so I have a 50 gallon corner aquarium and everything is doing okay. except that my alkalinity is too high and every time I have LPS they do fine for about a week and they polyp bailout on me (were they come off the skeleton). If anyone can help or suggestions it'll help a lot. My alkalinity is usually at around 12dkh

What supplements/dosing are you putting in tank? Read ingredients carefully sometimes they slip some in without saying on front label. As a side note I don't think 12dkh is causing the problem as I used to run my system that high because Red Sea test kits told me to and I didn't lose LPS

I don't dose my tank

Why are you running alk so high? Tissue necrosis can be due to several issues to include high alk.

 

Try running alk within 7 - 9 dkh.

I try not to run it that high. It's just hard to lower it

Have you tried using a salt mix with lower alk?  There are several available.  I am confident enough to say that 90% of WAMAS member are not running alk that high.

I don't run it that high because running at 9s gives me time to catch the alk slowly raising or lowering and allows me time to fix the issue. a lot of websites have suggest alk levels of 8-12dkh so an every day test at 12 would be ok. It would be risky not smart choice though because if it raises much higher there will be issues. One alk reading of 12 doesn't mean much to me. A graph of all alk readings at random times over months means more because corals hate the fluctuation. If the only thing you are doing is water changes I would like to know how large the water change is and I would do an alk check after. I feel smaller more often water changes are more appropriate because the alk,PH temp etc won't spike. There are 1000 more factors that can cause issues. LEDs were my first issue (learning curve). They were brand new and I had them cranked up. LPS doesn't like fried. It also could be improper/faulty test kits, a brand new coral with acclimation issues etc but I don't want to get off the subject

polyp bailout is a reproductive mode, not a dying mode. 

what is the alkalinity of the tap water?

 

I don't think he is experiencing polyp bailout.  Tissue necrosis.
