My 1st forum question!

Hi everyone!
Need your help.
I had a salt water pool that I converted to chlorine this year. In a 3 year span, I replaced 2 pumps, 2 cells and 2 control panels.
Inground pool, 25000 gallons, vinyl liner.
I was able to start my pool in 2 days and have clear water. After having it tested 3 times (store) , I'm still stuck with yellow/brown stains on the vinyl.
PH is OK, Chlorine is high for now, Alkalinity is OK. Very low metals, high phosphates.
I have used a phosphate remover, but my phosphate is still around 1500.
The stains change in size, from 10% to 40% coverage of the floor. I'm not sure what is the root cause.
How do I go at solving this? My pool store is not helping me, except telling me to buy gallons of stuff.

help!

First identify the stains. Start by rubbing some cheap Vitamin C tablets on the stain. You probably know somebody who has some. Ask around before you go buy some. Report back if it lifts the stain or not.

Thanks for the tip. I will try this tomorrow and report back.

It took me a while to get vitamin C and have warmer temperature. I did try and the area where the vitamin C tablet touched, the vinyl color was back to normal. What does it indicate and what are the remedies?

Thank you. I will try this. I must admit that I'm having problem stabilizing the pool chemistry since I move from salt to chlorine. The pool stores don't always give me good advice. I think I need to buy a good pool test kit like the Taylor K-2006. Is this a good kit or should I get another set from Taylor?

The K2006 preferab;y the C version is the kit you want. Be prepared for sticker shock. There is one company with a monopoly on Taylor stuff in Canada and they charge accordingly. Taylor kit in Canada?
