I agree with Brad, that swing over weeks isn't a factor, but what was you max alk level or do you know. I have seen big tanks done in by Alk burn but it wasn't realy fromt he level just going to high, but rather the Alk up powder not being mixed properly and landing on the corals. kinda looks like the tips start to melt and get stringy. I tried to find some pictures of the sump/dosing set up you have to see the locations you add your stuff, but couldn't find any. you young kids put so much stuff into your tanks now days it makes it hard anyways, GFO, Bioballs, ect....

also another thing is temp, it will do the same thing, have you had any spikes laitly? here is a pic of what temp did to my tank years ago



it started out with just the tips like an Alk burn then the rest started slughing off here was the end result.



this bucket is 24" accross



this one is 36" accross

by low i mean 7-8 obviously not 4 or 5


when running bio pellets or even zeolites(ULNS) it is better to keep it lower
