Re: My pS234 test results
Did you test your fill water? With such high alkalinity and calcium, it would be better to drain 1/3 of the water out, refill, drain 1/3 and refill and do it again until the alkalinity, calcium and cya are in normal ranges. If your alk and calcium are high in your fill water, then the only thing that will lower will be the cya - which is a good thing, because with such high cya, you would need very high chlorine numbers continuously as Carl says. I have a fiberglass pool and I have never had a problem draining and refilling this way. If you don't have a high water table, you can take it down a half at a time. With the high chlorine levels you will get false ph readings, therefore it really is in your best interest to take the cya down so that you can run your chlorine at lower levels without getting algae. When the water is balanced properly, it is much easier to keep a sanitized pool. We are here to answer any questions you may have
