Perfect! That does answer my question. The chlorinater does have a dail 1-5 to increase if needed. Would you be able to tell me on a average how long someone would have the setting set to have the pump on high to Increase levels? Example right now my polaris runs a total of four hours in a 24 he period , 2 hrs in the a.m. and 2 hrs in the p.m. That is the only time it is running on higher speed. Obviously this is not long enough to put enough chlorine in the pool. So I do understand about using liquid chlorine to subsidize or increase the level and let the tabs do the maintaining , but how long should I increase my higher pump speed time to bring the levels to norm?
