I just went through the painful process of draining my pool Through the help of the kind folks here, I was advised that I had too much CYA in your pool last Summer. I had to keep my chlorine above 10ppm all Summer (expensive).
We have a ton of iron on our water here, so my pool water started out dark brown on Sunday. Now, it is getting to be a light green and I am starting to see the bottom.
Here are my current stats (using TF-100 kit):
CYA < 20
I have already put about 5-6 gallons of liquid bleach since Sunday - about two gallons a day. However after 24 hours, I am back down to a zero reading. Is this normal. Any advice on what to put in next besides chlorine and how much?
