Hi Harlequin Mania, thx for ur encouragement. Reefing is always some kind of enjoyment and relaxation in my life, even a small tank, it can be a lot of fun too, as long it wouldn't makes you like a slave.
Just installed a 1/2HP chiller for my tank, my fishes n corals must be more happy now, but NO3 n PO4 should be slightly high as brown algea shows on the rocks n glass, necessary treatment will be taken soon.
Red n blue sponge are not doing well, any advice?
