Green pool after salt.

[CM_NOLA]

need help with green pool Pool was turning green. Was worse this morning. I tested water. Chlorine super low. Most likely because of the dearth of salt. So this morning I added more salt and then dumped some chlorine in there. Then the green got way worse all of a sudden. What is next move?

FC 5 CC 0 pH 7.3 TA 100 CH 625 CYA 90

With a CYA of 90 and low FC is the cause for algae to grow.
What test kit are you using?
Why are you adding salt? Salt does not prevent algae and depending what type of salt you use, it could add unwanted by products.
Also, certain chlorine products can be adding unwanted by products. It is best to use liquid chlorine.

The clear green is probably iron.

You probably also have algae.

Why would you add salt? Do you have a SWCG? What was the salt level?
