Ok so i have a 14 gallon bio cube and i want to upgrade the lighting. i have kinda looked into getting the Aqualight HQI Metal Halide Fixture the one that clamps onto the tank and getting rid of the stock hood or hanging a metal halide above the tank but that will create alot of heat which im trying to avoid as much as possible. or would the LEDs that clamp on to the tank be better if i get rid of the hood? and is there a lighting system that fits in the hood that have sps growing capabilites? because ive talked to some people that have LED upgrades but still cant grow sps corals. what experince do you guys have with your biocube lighting upgrades?
