Felix~ my 1st setup was Deep Water Innovations. Never had a problem with the airstones getting clogged just the pump that comes with it doesn't give enough air for two tray system. Very easy to use maintains ph really well . I do a reservoir change on a weekly basis just top off with plain ph water as needed. I had great results with Bubblegum. Hope that helps. Have a backup air pump because if yours fails to operate water will flood out of the try from the bottom.

DWC i am building a 40 bucket dwc system my question is do i put a air stone in each bucket or just a air line(no stone), cause a buddy of mine told me that the air stone will kill all the bacteria(and you will want some bacteria) and recommended me to just put a 8in round air stone disc in the 55gal reservoir and it will be fine Rating: 5
