Silly me...I did the arithmetic incorrectly...I have one lighting fixture that four 65 watters and another that's two 65 watters and another with a 40 watt flourescent for a total of 430 watts. I was thinking replacing the 40 watt fixture, which is the single flourescent reflector that came with the tank, with a new unit with two 65 watters. I also thought of replacing the four 65 watt unit (which is over the center of the top of the tank) with a four 96 watt unit, but because of the configuration of the tank and need for easy access into the tank from the front, that would still leave the front of the rock a bit shaded unless I add more wattage there (where the 40 watt unit is now)....I want to add the new two 65 watt unit to make more lighting available to the front of the rock. I don't see any need for the MH
's since I'm not keeping any really high light demanding corals.
I thought that there wasn't too much need for concern that the addition of the lighting would be a problem but your statement that there wouldn't be too much intensity with the addition of more wattage of PC
lighting makes me feel confident that it's okay...Thanks for the info.
