Joel, I buy from the same place. Nice peeps and they get it out to you in good time. They have a reg website. Go for the 6 plant drip system almost the same, under 60 bucks delivered. Landmsales.com. You can still put an air stone in to help I did. I just ordered 6 , 1/4 inch cut offs so I can hook up a hose to the fitting on the end and let the pump empty the system for me. A little easier to change water.
