That is true but ya everything looks fine and all my corals are doing great. My green ones when from 5-11 and my spiderman went from 1 to 2 with the power compacts and with the MH the green ones went to 11-15 and spidermans to 1 to 2. And their still on the top most rocks.
Lets say I just stick with this lighting, is their a placement where I should put certain corals??
