How far would a 175W HQI lamp penetrate into the water? I'm thinking not far enough for a tank that is 31" deep, right? I saw a complete set up that has 1 175 w HQI,(with tempered glass splash guard) 2-24w CF actinics, and 2 moonlights with cooling fans all in one lighting hood for a decent price. I'm just afraid it won't do any good in a tank this deep.
Any help would be appreciated. Only macros and softies will be in this tank as it is my sea horse tank.
TIA,
Angie
