What is the best way to get zoo's to grow rapidly? I have 350watts of PC on a 75 gal tank. 1 4 ft 4x55 watt. (2 10k, 2 Atc) and 1 30" (2 50/50). Outside of going to MH is there a good combination of supplements to aid growth? I just got some iodine, buffer, builder and advantage calcium from seachem. Is there anything elese you reccomend?
