Borax test Strips and cloudy water

[deep_blue]

Have learned a lot here but I had a problem yesterday...

I had a cloudy problem a few weeks ago and I shocked with chlorine to about
10+ (I do not use chlorine stabilizer, indoor pool) and after filtering and keeping chlorine at 6-10 ppm for a few days with filter on, it got better. Pool seemed to be a green cloudy water with white threads / looked like lint, observed in pool water. A algae or mold?

I use liquid bleach for chlorine.

Is 6-10 ppm chlorine in a non-stabilized indoor pool really high?


Next,
I purchased the Borax test strips and tested water at 10 ppm or lower.

I have thought that getting the Borax level to 40-50 would be good for algae, and pool staying clear and clean, along with chlorine, and proper water chemistry.

I added 2 cups of 20 Mule Team (indoor pool 3500 gals) and wanted to test the changes....So I have probably a total of 4 cups of borax in 3500 gal pool.

I also added PH acid ( sodium bisulfate to get PH to 7.4 ) after Borax and
the starting high PH of 7.8 from all my shocking.

Problem,
The pool became cloudy and I probably should have not spent time in the pool
at that time and now I am (dry itchy, and skin is pretty red)

What do I need to do for the cloudy water?

What did I mess up on? or miss?

And finally, does rust from some Stainless Steel screws and such need to be removed with a metal out type product?



CL 4
CC 0
PH 7.4
TA 80
CH 100
CYA 0 (indoor)



Thanks in advance
