I have a Purple Plasma that is currently starting to bleach. Its losing its color slowly. Its high up in the tank under 150 DE Mh. I have a 90 gallon. Temp is 78, Ca 400 alk 9 mag 1400 nitrates 0 and phos .01. As far as i know all my levels are on key the only thing i can think of is that i dipped it in iodine. My question is should i move it into lower light if its starting to bleach or should i leave it alone and hope it recovers?
