I’ve been maintaining my pool for several years and I occasionally have to treat my pool for algae and recently started using cal hypo tablets because the cyanuric acid levels have become too high using tri-chlor tabs. As you know, the cal hypo tabs dissolve quickly and im not sure of this is the solution to avoiding the build up of cyanuric acid. I don’t understand how our former pool guy was able to come once a week and not have the issue of high levels of cyanuric acid. I’ve had to drain my pool because of high levels. Am I missing something or do I just need to stick with using cal hypo tans from now on to avoid the build up of cyanuric acid?
Any advice would ne much appreciated!

The cal hypo adds calcium which builds up the same as the CYA. TFP recommends using sodium hypochlorite (liquid chlorine/plain bleach) or a salt water chlorinator for those reasons.
 
As Keith above said do be careful from the buildup of using Cal-Hypo tabs in feeders that previously used Tri-Chlor tablets. You usually see warning labels about mixing the different tablets on feeders. Also what Bperry said with using the liquid chlorine (sodium hypochlorite) as the main source of keeping the pool maintained will be more beneficial for a balanced pool then overuse of the Tri-Chlor Tabs. :swim:
