My tank has been up since the beginning of December 2012 and in the past few weeks I have had a few pieces of coral bleach out and I can't figure it out. So lets start out with equipment and parameters:
34 gal solana
MP10w
Tunze Osmolator
Tunze 9002 skimmer
AI sol blue (10" above water)
carbon and GFO for chemical filtration
sponge replaced daily, filter pad replaced 2-3x per week
Water parameters are fairly stable at
7.5 dKH
425 ppm Ca
1300 ppm Mg
5 ppm nitrate
0 ppm Phosphate (via Salifert)
Water changes are 5 gallons weekly
Lighting schedule
(Time start/W/B/RB/ramp)
10AM/0/10/10/30min
11AM/10/15/15/30min
12PM/35/40/40/60min
4PM/30/35/35/60min
8PM/10/20/20/30min
9PM/0/5/5/20min
10PM/-/0/0/25min
My temp has been at 82 for maybe a week or two, the thermostat on my heater is busted, and I am getting an APex JR tomorrow to keep temp at 80F.
OK, so finally we get to the problem. Some stuff is thriving and some is bleaching and I cannot figure it out. I have 4 chalices low in the tank in very similar lighting and flow conditions, 3 look great, one is bleaching. I have 5 montis in similar light/flow. Monti cap is unbelievably bright, chili pepper is fantastic, sunset is great, undata is growing, but very poor coloration, rainbow monti is only rainbow in the sense that white can be said to contain all colors. Frogspawn is fantastic, went from one head to 2.5 in a few months, the golden torch 3 inches away looked great and has bleached over the last week. Magicians palys are great, blue palys are losing color.
You get the point, many corals are great while closely related corals in similar conditions are doing poorly.
Other corals that are thriving include duncans, favia, mushrooms, pavona, GSP, xenia.
My livestock includes a yellow watchman goby (that I have not seen for a month since he was rescued from the overflow, a mandarin dragonette (eats frozen food like a pig), a tube anemone, and maxima clam.
Any ideas? My only thoughts are temp was too high for a week or two, or my lighting schedule is no good...
