Need advice filling pool with Florida sulfur well water

[BruceandBuddy]

Doc,

This morning the dip stick measured 0 CYA - Last night I put in 52 oz of 25% CYA and this morning I did the same - tonight the stick measured closer to 0 than 50, so I conclude that there's enough stabilizer and no more was added tonight.
The FC measured 2 ppm this morning and the filter was much lighter (but still I'd say toward red rather than brown). I put in 2 ppm worth of Cl this morning and the water measured about 1.5 tonight. Tonight I put in the 32 oz Cl, which calcs to about 5 ppm worth. So, I take it we're SLAMing the pool at about 7-8 ppm? The pH had come down because of rain, it was about 7.6 or slightly more. Tonight the filter was brown stained. A picture is attached ... sorry it's not because I don't have a url for my pic - sorry ... nerd again.

Thank you for helping me through this - the water looks nice so far and there’s FC left at the end of the day
Someday soon I'll dive into the PoolSchool....

BTW- I just ordered the Taylor K2006
