We just had our pool installed a few weeks ago by a local pool company. My initial experience with the installed "pool frog" system resulted in a bunch of brown dusty deposits all over the bottom of the pool, so I started looking online for a better solution and found your website. Long story short, I've been studying your pages and have become a happy convert to the TFPC method.
After a week of testing (TF-100) and after SLAMming the pool and adjusting things using walmart bleach, I think I'm almost there but need some guidance.
The pool passed the OCLT a few days ago and the FC is coming down very slowly.
There are still a few light brown dusty deposits on the pool floor but I've been brushing and running the robot and they are going away.
My most current levels are:
FC = 8
CC = 0.5
PH = 6.8
TA = 30
CH = 100
CYA = 30
Some more info:
1. A couple of weeks ago when I was still using the pool frog, I added a liquid mineral pack (copper I believe), so that's in the water for better or worse.
2. The frog is now set to OFF.
3. Originally, the CYA tested at 0 so I slowly added (hanging sock) 4 pounds of wal-mart stabilizer a few days ago after the OCLT passed.
I have a 40 lb bucket of Pro Team Supreme that came with the pool.
My question is, should I add the Pro Team Supreme since I have it? Or should I use something else?
I think I remember the pool store guy saying it would raise my PH levels which seems like a good thing to me since they are low.
Also, what else should I be doing to get my levels in line?
Thanks very much for your help,
