I have a 55 gallon saltwater aquarium with a Snowflake clownfish and a Coral beauty angelfish. The lighting a 24in 50/50 coral life bulb on a 48 inch long aquarium but it only runs Bright no night time setting with the fixture (Non-changeable spectrum). The water parimeters I have for the Aquarium fit with the fish I have. I have dry live rock, Aqua clear 70, Marineland c220 and a hydror powerhead, I do use RODI water. If the tank would be able to House coral or a anemone which type would I be able to get? If not, what would I need to change with the aquarium and what speical kits or water additivies would I need to get? Thanks!
