thanks a lot guys, I think I will go with some combo lighting... Would something like 10K MH's coupled with what spectrum T5's be best? I have a 20K xm MH bulb that is 250 watt and it shines this really awsome blueish color, but I dont know if that blue will grow everything like a 10K bulb, wich i dont like the yellowish color that they produce as much. So would I be better off getting the 10k and making the tank more blue with t5's or using the 20k or 15k and adding some 10k spectrum with the t5's?
Thanks a bunch
