I don't mean to jack the thread but I think my question goes along with the original post's question.

Any way to DIY an air stone? looking to cover the whole bottom of my tub.

Booyagrandma Reviewed by Booyagrandma on . Quick Question on Airstones? Hey, I was wondering how important it is to have a good airstone with fine bubbles? Because I am modifying my system and I need to add 8 new airstones... and I would rather not spent $50 per airstone for the ones that produce fine micron bubbles. What is an acceptable micron level for growing plants hydroponically? If anyone has found good cheap ($20) airstones that work I would be forever grateful :stoned: Thank you all for your time.
