I cycle my tank with SUmp, LR (3KG) and Sand bed 3", and put market prawn inside, after one week test amonia at light green colour level, will put more LR in future, very costly to set up a marine tank , my main tank size is 2 2x 2ft with 2x1x1.5ft sump, already spend S$1000, (with second hand 1/4 chiller) ,now no $$$ liao, very poor.......ya, I DIY PL-L light...
Just wonder for such a tank size how much you all spend??
