If you soak them in kaboom or some sort of solvent and then wash them off well they should unclog.
Specialist Reviewed by Specialist on . Air stones clogging Hi everybody, i've been growing hydroponic for a while now, and i'm facing a serious problem. The air stones clog very fast, so i've got to change them often, and if i don't notice that they are clogged, my air pomps are damaged, and sometimes dead. Do someone know why air stones clog quite fast, is there a way to avoid this problem, and what can be the problem in the air pomp and is there a way to fix it ? many important questions. Thanks Fhydro Rating: 5
