Clogged Air Stone

[Andyd]

I bet it is too small a micron what ever the thingy's are ( size of holes in the airstone)
I scored one from the states and I needed a mother of air-pumps to drive it,scored one of those as well.
Works a treat now and has done for many years,greenhouse foot print could be better.
This was before we had oz retailers selling such things.

Hey Batz,

What sort of pump did you get. I've tried to Aqua pumps now and neither one gives me the output I'm after...
