My temp has been between 81-83 degrees. Is this a problem? Will it not help the growth of my corals and zoos? Most of my corals are doing well but I do seem to see that soft corals like my colt coral are regressing! I donÃ¢â‚¬â„¢t know if it is the temp or what. I check my tank water parameters almost every other day. All parameters seem to be fine.
