Active Aqua 2x2 airstones
I use 2 of these 2x2 round stones in every bucket that I run. I have been really overpaying for them until I happened to get recommended one of Gary's videos on YouTube and went straight to the site. I have tried many different airstones and lots of them don't work to fill potential where these get the job done. I'll continue to buy them and always from PA hydroponics!
