I use hydrogen peroxide (H2O2), a bristle brush, and boiling hot water to clean my stones. I boil em, scrub em, douse them, and then run air through em for awhile in a H2O2 solution. Micro can definitely clog em.

For getting scrum off the walls, use a water and H2O2 solution. When I did hydro, I cleaned every week. The bubble wands dont clog as easily but they seem to have larger bubbles. However they seem nice considering they wont crack or break or keep stuff inside of them.
Racerx Reviewed by Racerx 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
