I have a 35 Gallon Hex with a Skilter 250, 40 lb. of live rock, and 40 lb. of live sand. I have had the tnak now for more then 4 months. I do not like the clarity of the water and do not think the skilter is working well. I always have to adjust the air intake valve and there is always debris floaitng in the tank. Do I need a UV sterilizer or different filter/protien skimmer? What is the best hang on protien skimmer? Also what would you suggest for the best lighting. I have a corallife 24" light which has both the white and blue light. I would like to keep both corals and fish in my tank. Thanks any information is greatly appreciated.
