于 2002-03-19 15:17 If yours is a FOT then using Live Sand with 充水層(Plenum) may not be a bad choice provided you don't keep a too many fishes. Details can be found in PH8.4.
I started my 150L FOT tank about 6 months ago with only a power head and skimmer. Currently there are 6 fishes (from 1.5" - 3") and they are doing well. NO2 = 0 and NO3 ~ 20.
