I bought a new house and had the pool redone with a Sand colored quartz. Its been 2 months now and everything has been great until rains started happening. My phosphates went up and small yellow stains began to appear all over the pool.
I went to Lesie's Pool Supply and got a test. They said it was Mustard Algae. They told me to raise my PH and Alkalinity and shock with Yellow out. It's been 4 days now with no difference. The spots do not come off with brushing and do not feel any rougher than the rest of the pool.
I have read if you put a puck on the satin itself it will disappear, but that didn't work so I tried rubbing Vit C on it and that didn't work either.
I went back and had them test for Copper. They said I had a little copper, but why wouldn't have the Vit C tab worked?
Ive looked all over these forums with someone similar to mine and I cant find anything.
My questions are:
Do I need to be patient and let the shock work? I was told they would be gone in 48 hours.
Why didn't either of the "tests" (Vit C tab and the Puck) not work if I have copper?
At this point I'm lost and about $200 in. I have not put the metal out and sequester in that I purchased a couple of days ago from Leslie'sin yet because I thought I would ask everyone here. Can someone please help me? Im very new to this and need help.
Attached is what my pool, pool equipment and what the stains look like and my initial test results.
