Well, I got tired of missing the small supply DV kept receiving. And I was not gonna pay $20 for 3 skinny wicks. So today I went to petsmart (first time I ever been there I don't have any pets). Bought the top fin airstones for $3.99. I cut it in half and got 5 wicks out of it. This was my first time cutting these so maybe I could of gotten more. I made 2 that are 5/32" to fit the large wick hole of the ac9 clone. And I made 3 at 1/8" to fit my agaT2 and ac9 rba's. Cutting that sure did kick out a lot of dust so I had a mask so I wouldn't breathe in all of that. I think I saved a bunch of money today and I still had another half of the stone I can use later.
