I have been using 3" Trichlor tabs in my Rainbow chlorinator and performing my own testing with a basic 4 kit for the five years we have owned our pool. Last summer was the first time I've had algae issues, thanks to a complete drain and refill for a pool remodel several years ago that kept the CYA in check for a time. I took my water to the pool store multiple times for testing and received a different answer each time regarding the cause of my algae. Thankfully I found this site and figured I must have high stabilizer levels and would need to do a partial drain to remedy. But with a new baby joining our family last summer I wasn't prepared to deal with it, so here I am.
I just received my TF100 kit and performed the first tests today. The water is clear with a tendency for algae in the corners of the steps and on the Polaris bag. My results are:
My question is this:
I know I need to do a partial drain and refill to get both the CYA and CH in check, but we will be out of town for two weeks at the beginning of June. Do I do the drain and refill now, start chlorinating with bleach, and then use tablets while we are gone? I don't know how else to chlorinate the pool while we're away. Will two weeks use of tablets raise the CYA back up by much?
