I replaced my metal halide/T5/LED combo for an 8 bulb ATI Sunpower. The PAR is identical to the previous trifecta and I am now using 432 watts of power versus 770 watts. I also added a GFO reactor which is also running ROX 0.8 carbon as well as dosing vinegar via the dosing pump.
Everything is going great in my 40 gallon breeder. I just added a Jebao dosing pump to keep up with the alkalinity and calcium demands of the corals. Still no protein skimmer, just a 30 gallon sump full of live rock and chaeto lit by two PAR 38 flood lights!
