I have successfully moved from the pucks to liquid chlorine and finally have CYA under control (running about 55 right now) after being fed up with constant water changes. Under the relentless Texas sun I am consuming about 2 quarts + of 8.25% bleach a day, and I target my chlorine level every evening at 7-7.5. I have checked and the level doesn't change overnight, so nothing is in the pool that is consuming the chlorine. I attribute almost all of the loss to UV and temps (water is running 86 deg. right now at air temps are hitting 105 deg. F). My pool is about 18,500 gal, plastered. (and ... water is beautiful and clear)
Here is my question. The up side of pucks is you can drop a few in a float and walk away from the pool for a week without worry that you'll return to an explosion of mustard algae. Right now I am nailed to the house. I can't leave! I have to test the water every day at least once and add the chlorine in the evening. Is there any kind of system that will add the chlorine "automatically," or is that called a "neighbor." Also, I have a Taylor test kit. The stand-in has to learn how to use Taylor testing system.
Anybody out there solved this problem? How can I walk away from this thing for a weekend trip and not return to an algae pit?
