How often do you change your carbon and phosphate media??? Carbon only need to change once a month and phosphate media only change when your PO4 reading rises. Otherwise if you keep changing both media monthly, it will burn a large hole in your pocket.
Oh ya, btw, supersuns dun need to be fed everyday. What I do now is to feed them meaty food like mashed fish/henrys/combo and then for the next 2-3 days I just feed them rotifiers, copepods etc. In this way, I will be sure that I do not overfeed them.
