On my tank I currently have for lighting I currently have 1 48inch PC 4*65 watt, and one 4 bulb HO t5 24inch bulbs i forget the wattage...
My question is this. I now have an option to get a 175watt or 150watt metal halide system.
I want my tank to be mainly zoos. So I was thinking that my current system is good enough but I want to get a some more opinions/advise before I lose this chance.
Please help me
