juz a piece of advise b4 anything happen, u may wan to hold on to this tank for a longer time. dun try to shift all ur ls to the new tank right after cycling. the sudden high bioload may cause ur perimeters to go haywire or No3 shoot up faster than rocket....that the reason why ppl also tell newbie to stock up slowly when they juz set up the tank.... i took 1 mth to transfer my ls from my 2ft to 3ft. of cos this 1 mth abit siong cos need to run 2 chillers, skimmers.......
