First off, I am very new to coral & SW
tanks in general - this is my first reef tank/SW
tank. I bought a nice hammer coral from my LFS
yesterday and it opened up somewhat yesterday after acclimation but never as full as it was in the LFS
. Today I came home from work and it is not open at all.
tank, 20 gal
sump. Newly established (running for about 3-4 weeks). Stock is only 2 small percula clowns at the moment and some tiny hermit crabs.
Lighting: 2 AI SOL pods
, set to 50% white 65% blue intensity. 3 hour ramp up from 0 to that, 4 hours at that intensity setting, 3 hour ramp down to 4% blue (moonlights).
Flow: eheim 1262 return and 2 Vortech MP10s running on ECOSmart mode during the day, night mode at lights out. Powerheads are each 4-6" under the surface, pointing roughly at each other, and set to ~70% of max speed.
Skimmer: BG NAC 3, collecting about 1/3 cup a day
All other corals seem to be doing fine and are all open: several zoa colonies, some daisy polyps, and a frogspawn.
So any thoughts? Too much flow? Not enough light? Too much light?
