I'm not sure where to post this ?, but are there better solutions for adding chlorine to my pool other then this? Hmmm, not letting me upload a picture. I never seem to have enough chlorine even when this is turned up all the way and 5-7 3" tablets in there. Not sure why I can't upload a picture. Anyway, its a Hayward Chlorine Feeder for 3" tablets. It has a dial on it that goes from off to 7 I think. Very small 1/4" tube attached to the 2" PVC pipe off the pump (water inlet) and then another 1/4" tube attached to the 2" PVC pipe going back to the returns. Everytime I check the water there is no chlorine.
