Hello RB, I have a quick question, I am setting up a new tank (30 Gal, 24 L 24 W and 12 H). I plan on doing a 1-1.5 inch sand bed, and hanging the light pendant style. Would a Photon provide too much light? Would I ever be able to use "100% " of its power, and lastly would the Photon 24 be able to cover the entire spread of the tank with 90 degree optics? Thanks, G Looks like your item is back ordered, any ETA other then what is stated on your website?
