i have been reading up on the reasons for your recommendation of using liquid chlorine instead of chlorine tabs. We have been using the tabs in an inline feeder. We had a pool leak and were adding water daily, so we have never had an issue with the CYA rising. We have fixed our pool leak so I recognize that it could potentially become an issue. We obviously do not want to do anything that would cause the algae to reappear. My question is, for pools that are open May-Sept. and are partially drained in the winter, is this a concern? Could we continue to use the tabs this summer, monitor the CYA weekly (CYA level is below 30 now) and if it does not become an issue before the end of the summer, see what the level is after partial drainage and refill next May and make a decision about the need for using liquid chlorine then or are there other concerns? I’d like to avoid the expense and hassle of switching over if that is possible but don’t want to have algae growth either.
