Two Part Solution Problem- Help!

[straightrazorguy]

So, the Alk has been in the 7-8 range for over a week now and the STN continues. I fragged my slimer and some other acros, covered the skeleton part and part of the healthy tissue with Ecoteck coral glue and glued the frags. The STN continued past the glue on the frags and continued on the mother colonies too. I'm out of ideas and really bummed out!

My paramters are where I want them: Ca at 400-420, Alk at 7-8, PO4 at 0.03, nitrates undetectable. I fed aminos, I fed my fish heavily, etc. to no avail.

Ideas? Suggestions?
