Hi, I signed up today, and this is my first post.
I've owned my pool for 16 years, but I began reading about TF pool methods last year when I had a really big algae bloom. After multiple cycles of PhosFree, I decided I would educate myself on the TFP maintenance process and try something different this year. I ordered the TF test kit and received it today. I already knew that my CYA levels were high from tests at the pool store, but I wanted to confirm with my own test, and CYA is well over 100 ppm - I think pool store tests put it at 150 ppm (which they also say is quite low and fine). I also tested everything else and these are the results in case it matters for anything related to this:
FC 3 ppm
CC .5 ppm
TC 3.5 ppm
CH 425 ppm
TA 80 ppm
I've been searching for best ways to remove CYA from the pool, and I think that removing / adding water is the best option for me. There is a method I'm considering that I haven't seen mentioned specifically anywhere so I wanted to get additional thoughts on it. My pool has an overflow drain. With the pool pump turned off, can I just put a hose at the bottom of the deep end (about 9' deep) and add water to the bottom of the pool which will raise the level and push older water out of the overflow drain on the surface? I realize that there will be some mixing of water in this process, but it seems like this would be easier and safer than draining a third of the water and then refilling or using a tarp of some sort. Appreciate any feedback you may have.
Thanks,
Travis
