In the ocean it may take quite a depth to make a difference, but aquarium light bulbs are no star.
Im with harif on this one, WPG doesn't hold so much water  |
I agree to an extent. But we are not dealing with N.O. lighting either. (Thats the main reason wpg went out the window). Wit power compacts or higher (which the poster stated they have), Depth isn't the issue, coral placement is. Your mushrooms could bleach out but its impossible to have a tank where anything can be placed anywhere. Some corals like higher lighting, some dont. Even with MH you have to place some lower than you would with VHO and vice versa. With tanks 48 inches or less there is no problem with penetration of light with PC bulbs or better.
