I got several frags from a friend 6 weeks back for my14 gallon biocube w/ upgraded PC lighting -5 watts / gallon.All the softies are doing well- candy cane, torch, frogspawn, green finger, however a montastrea frag has started to bleach out and I am concerned its not long for this world. parameters-1.025,78- 80degrees, nitates 0, Ca 410, pH8.2, plenty of current, 15 % water changes w/ distilled water q 3 days and instant ocean, feeding 2-3 times per week with kent marine zooplex mixed with freeze dried cyclopeeze. I have the frag about 4 inches from the surface. I am afraid I just dont have enough light for it to survive- the middle 5 polyps have bleached but the surrounding polyps have held their color. Any ideas?
