New Vinyl Pool Owner with High CYA and High Water Table

[PAGirl]

sounds good. My current numbers are as follows:

FC - 12
TA - 80
CH - 30m
CYA - 30
pH - 7.6

According to the CSI calculation I am currently at a -.6 with a CA of 30 ppm. Is there any harm to me leaving the water soft and not adding calcium chloride? I am assuming this will help in the dissolving process?

Earlier you reported your calcium at 270?

that was before I drained the pool. I had to bring the cya down significantly. I have yet to anything to raise the hardness level

In a vinyl pool, a low CSI does not matter. If you see foaming, then raising the CH some could help.

 

[obaro15]

What about low hardness? What negative affect will that have on the pool/people?

 

[jblizzle]

It does not have any effect.

My pool water is starting to clear up nicely but the white residue remains at the bottom of the pool. I have been vacuuming and scrubbing but it does not appear to be getting any better. Any thoughts?

 

[PAGirl]

Have you ever done a deep clean of your filter? Can you vacuum to waste?

The very end of aSLAM seems to crawl along.

I have not done a deep clean of my filter. It runs at ~5psi and I added a cup of DE to bring it up 1 PSI. I can vacuum to waste but I normally do not.

We bought this house in December and the pool looked great when we walked through the house in Sept. It was closed the previous owner (I am assuming he paid someone, but cant be sure). When we opened it up lat week we found this white film.

If it is calcium on the liner, maintaining your pH at the lower end of normal range may S-L-O-W-L-Y help resolve the problem.

 

[obaro15]

May? Slowly? This all sounds awful! Are there any other options besides changing out the liner?

My SLAM has been completed and the water looks amazing. The white residue is not moving. I have lowered the pH to 7.2. Any idea when I may see an improvement?
