The tank is completely new I unwrapped it myself. The pumps are rated for 1800 gph but they dont push that much out of the return they push about 1000.
The flow in my tank sucks because i dont have the cash right now to purchase a lot. About the angel it has only been in the tank for a night so hes not the problem.

the lights are six inches above the water im wondering if it gets too cold at night and thats what it is happening to the corals cause it sits at 78 in the day im just wondering about at night hmm?
