I'm wondering what would be best for my 100gal as far as most light for the buck. I'm considering the WH7 or WH8 ballast and ODNO 6500kT8s. What I really want to know is what's the best configuration.
The WH7&8 both output 220watts, but the WH7 has four power leads and the WH8 has 6 power leads. I'm thinking I could use 3bulbs and have 2wires per tube w/ the WH8 rather than going w/ 2 tubes (2wires per tube) or 4 tubes (sinlge lead per tube) w/ the WH7. Just want to know what you pros recommend
