Driers are a love hate relationship. You need to bake the dessicant to get the moisture out, and its a time consuming proccess. Better if you have several pounds of it that you can keep dry and do several media changes before having to dry it all again. Use a vapor tight container to keep it in. And try not to draw the air from the humid fishroom but from in the driest part of the house, or outside if its a cold dry climate. Also what happens in the generators is the ozone reacts with the nitrogen in the air, creating nitric acid, which will even eat stainless steel. This, along with the salt in the air of our fishrooms causes corrosion in the units. In commercial units, they use oxygen concentrators, removing nitrogen and moisture. The PSA (Pressure Swing Absorption) concentrators lower the dewpoint very low, thus a win/ win for the ozonator. (Same machines used for breathing aids, and why those have humidifiers built in) This slows corrosion and makes more ozone from the machine than just air. I havent looked into the RK2 units or Ozotech. I imagine that for the cost of those, you can clean them.
