I am looking into upgrading my tank which I am pretty serious about that this point in time. I have (3) T5 lights at 50 watts each over a 125 gallon tank. I just swapped out the gravel substrate for SMS substrate. I am getting ready to purchase dry ferts so I can start dosing for more than just micros with Flourish and last but not least I am going to get a CO2 system. My question is though, is 150 watts enough over a 125 gallon tank with the CO2 and ferts? Thanks!
