That purifier will prob work as well as pissing into the wind and trying to stay dry :wtf:
You need some type of charcoal filter to knock the smell down. Are you setting this up in a spare room? closet? or ???????
The more O2 you can get into the water the better so if your air pump has more than one outlet or strong enough to branch off of then add another stone. I have a 55 gal res and last run I had 2 6" Bubble bars and now I'm running 2 12" bars. Lots and lots of bubbles is what you want. You dont have to go quite as strong with nutes in DWC as you do with other styles since the roots are always in the nuted water and not just getting "fed" 4-5 times a day. If you want when you start everything up you can start a grow log and we all can follow along and try to help where needed. Other than that .................. Welcome to Hydro :jointsmile:
