Hi all THe hood for my tank collapsed and I lost all my lighting ( 8 * T5's -54 watts) on Sunday. Since I want to upgrade to LED's sometime this year,I decided to get a second hand unit which is 1.8m long and has 3 x150 MH and 4 T5's on the sides(2 on each side) as an interim solution. My tank size is 2m long (Length) and the depth(height) is 80cm. Currently the unit is hanging +-20cm above the water level. The lighting doesn't look as bright , so I need to find out if this lighting provided by the unit is sufficient for the following corals which i have as some of them are at the bottom of the tank: frog spawns, xenia trees, kenya coral tree, mushrooms and zoas.
