I too am baffled why some corals and frags do well and some don't. I have purchased several frags and mini colonies (red planet, blue millie, pink bird nests, ORA purple thick branched birds nest, sunset monti, green monti) from ARC members that have gotten out of the hobby and some are doing well great PE and color, but the ones I really want to do well (red planet and blue Millie) lost their PE after 2 days and are just barely peeking out but nothing like they had while the were floating in the bags in my tankwhile acclimating.
Water params are constant:
No3 - undetectable with Red Sea pro low range phos kit
Po4 - undetectable, running GFO (Rowaphos) in a reactor
SG - 1.026
Temp - 81
Ca- 460
Ak- 8.5 dkh
Mg - 1600
Have 2 3200 gph dual flow wave maker power heads on the way to increase turnover in my 125 gal with 40 gal sump system, but already have 6 power heads plus my 1100 gph return pump.
Does anyone have any suggestions?
Want the same results I see in others' tanks.
