Just setup my tank and using iwaki 40RX (1/2 up water, 3/4 down water), Resun C450, 220L main tank, 80L sand tank, 150W HQI, Tota 3 tube T5 FL tube. DSB and mainly for Coral. Now total expense is around HKD7000 not included coral yet.
But very enjoy is, all ducting installation and drilling the glass is DIY. Very time consuming but fun
