i checked with my local saltwater aquarium store and they said everything (temp., calcium, magnesium, etc.) was perfect except i still needed to add some pH buffer weekly and normally... and i have the best lighting system around! i have the Aquaillumination LED
system and the light changes daily representing morning, day, and night with "white" lights, "blue" lights, and "royal" lights. and for flow i have a VorTech MP40. but, with that said, the powerhead is on the opposite side of which my green favia coral is on. so i doubt it's getting a lot of flow... any advice with that?
