It was a process of elimination. Our refractometer was off to begin with but we had just upgraded to a 240 gallon and changed sands. We assumed that was the problem and After a few months started to see improvement We still had algae problem That began when we switched to reef crystals and Our acros were still stressed. We decided to start intergrating coral pro through water changes. Our sps went from bleaching to flaking. The encrustations and skin looked dehydrated. We tried everything, Rtn destroyers, additives, replacing filters on Ro system, amputations, dips, adding beneficial bacterias and adding more pest predators. In a last effort we took our water to every Lfs for testing and only one of them checked the salinity. In the panick of our corals dying we managed to miscalculate the salt in the previous water change and our already high salinity rose up to 1.036. We were lucky and only lost one colony and a cple frags completely. Such a dumb error but without it we may not have noticed that our refractometer was off and would still be scratching our heads at the patches.How did you find out?

What's your zinc from the Triton test? I suspect zero. Eshan mentioned at MACNA that he theorizes low zinc and high alk is what leads to burnt tips.
It was 3.13 on the triton test and the target is 4.0. They labeled it as in the "green" range so I guess it's not low? Never really looked at zinc so I'm not sure how much deviation is bad
Aluminum is in many people's threads that are having issues. It's nothing to do with po4 I promise you. My po4 has never been anywhere near as low as yours. My last po4 test was .55 ;) it only ceases growth. That is it.
I've been known to be right. :cool:I think you may be right. I thought I had turned it around. I did several water changes and began running carbon religiously again and things started to improve but my phosphates started to rise so I started using phosgaurd mixed in with my carbon and it seems to be happening again. The only other thing I has done is dose nitrate to get them to a detectable level. They are currently at .5 I took the Phosgaurd out and am going to mix a small amount of GFO into my carbon to help keep phosphates in check and see if that helps. At this point I think it is either the phosgaurd or the nitrate dosing although I'm not sure how the nitrate dosing would cause while spots, I would think it would cause algae which it hasn't.
