So mad! Pool man came by for the last time. He's sticking to his theory that I need to change at least the sand, preferably the whole filter. Pretty sure he's completely full of ca-ca (and I don't mean calcium
). I told him about the CYA level being 90-100. He didn't really have a good reason for it, but before he left, he had replaced the tablets in the floater. I thought I read somewhere on here that those tablets have CYA as well as chlorine.
Have I been completely scammed by this guy for the last nine months?
Welcome to the forum.
How do you know what your CYA level is? Pool $tore results? Unfortunately pool store results are usually not accurate at all, and you need to get one of the recommended test kits.
Test Kits Compared
I recommend
the TF-100 from TFtestkits.net with the XL option. The Taylor K-2006 (which I own) just doesn't have enough reagents, especially if a SLAM is needed to eliminate algae.
When using 3" Trichlor tablets, for every 10ppm of FC added, you are also adding 6ppm CYA.
If your CYA is indeed 100ppm you will need a daily (clear water) FC minimum level of 7ppm, with a target level of 12ppm, and your SLAM FC level would need to be maintained at 38ppm.
If that CYA level is correct you will need to consider a large amount of water exchanges to get that CYA down to a reasonable level.
Chlorine/CYA Chart
As mentioned, stop using chlorine tablets. All you need is liquid chlorine, aka bleach.
How to chlorinate your pool
Until you get a reliable test kit it will be next to impossible to address your water issues. In the meantime you can add one large jug (96oz) of 8.25% laundry bleach daily to try to keep things from getting worse. This will result in about 5ppm of FC added with each jug.
Also be sure to read up on
How to SLAM your pool to eliminate the algae.
Be sure to read through all the articles in
Pool School to prepare yourself to properly maintain your pool.
While it may seem overwhelming at first, once you start TFPC you will be amazed at how simple it is to maintain a sparkling clear pool.
