Hello all. For x-mas i got a 6x55w PC
light for my 55g tank so ive finally been able to get corals! I got one every few days since xmas and now have a frogspawn, pulsing xenia, trumpet coral, green open brain, sun coral, and a sps frag
1) The open brain only extends its polyps at night... is that normal?
2) i got the sun coral yesterday and it hasn't extended its polyps all the way yet. I have seen a few start to stick out, but not all the way. Should it be taking this long?
3) also, do you think 6 watts/gallon would be enough for sps
if they are near the top?
ty very much!!!
