help sps bleaching from base up

[carpus]

hi, my sps are bleaching from the base up. I already dipped the corals to stop RTN and I'm about to do some water changes and then add in a nitrate sponge. I hope its an water quality issue, since I lost a tang when I was on spring break and came home seeing my monti bleached. Now my acro and pocci are showing the same symptoms.

Any chance it is not a water issue... say a parasite.. red bugs... whatever. Thanks

Around this time of year, most tank are undergoing an increase in average temperature. I would also check magnesium, alkalinity and ca.

What's your phosphate,Calcium, Alk, etc...? My phosphate levels were high at one point and had the same problem. Then again I had the same problem when my Alk was low too. You really need to post your levels if you want anybody to be able to help you.
