Hello all! I am new to this group but not new to growing. I have been growing in hydro for 3 years on a small scale. My backup reservoir was a large garbage that was emptied completely and sterilized often. I am now growing on a much larger scale and my reservoirs are now 7-55 gallon drums connected together. The bottoms are not flat so there is some amount of water that never gets fully drained. I understand anaerobic and aerobic bacteria and while I have no serious slime, I know my reservoirs are not sterile. I have heard of people using bleach or chlorine HTH pool shock. How much should I use? I currently add Watermax to my hydro systems every other day to combat my stagnant water situation. I used to use it every 5 days. Do I need to continue using Watermax at all if my RO water already has chlorine or bleach in it? Any help would be appreciated.
