is any of the phos brand keeps allows permanent dumping of the stuff in the tank? i.e. i dont need to throw away the phos. even if it is exhausted so can be used as a biological filter. Furthermore, is there any phos that is not exhaustable?
I got a fox fish that suddenly have 'excreted' thin layer of 'skin' from its body, from fin top and bottom. The 'skin' looks like some excretion from carribean sea fan white transparent thin layer. Anyone knows what is it and what happen?
Thanks.
picking dead skin..hm...come to think of it there is a kind of fish rear in spas or qianhu that feeds on your dead skin legs...maybe can rear the shrimps to do the same job!
