I just purchased some SPS Corals. A couple of plating montis, a green slimer and a staghorn acro.The Temp inside my NanoCube 28 HQI will sometimes reach 81 degrees. Is is bad for my SPS corals????? My zoanthids and LPS have been doing really well with NO signs of problems. I have an Azoo Cooling fan running and have switched from running two Koralias to a Vortech MP10 to reduce heat. I really want to try an avoid a chiller but have even thought about switching over to the NanoTuners LED Retro Kit to reduce heat.
