White hard buildup on vinyl liner

[PoolDoc]

small granules are fine -- just put some in a clear glass and add vinegar, and leave it overnight. We really need to establish what the granules are, b4 you refill.

It would be a good idea to seal the glass with Saran-type wrap.

It did not dissolve in the vinegar.

And I had already went to bed so did not get the message to cover it.

Update got some bigger flakes off and they fizzes in vinegar and dissolved leaving nasty green stuff left. When putting some in water it turned water green but did not dissolve.

Ben-

My husband said you were going to post some pics and some instructions. Will that be on this thread or a new one? The pool is about half way full. Will continue filling today. We are on a shared well, so we can run nonstop overnight, but during day, we run for a few hours at a time so the neighbors don't complain.

[PoolDoc]

Yeah. I'm going to post it here. I ran out of time yesterday, and am supposed to be gone most of the day today.

But, keep filling and
#1 - Keep your pH low-ish => 7.0 - 7.2 . Add small doses of acid to maintain this. I told your husband how to use muriatic (plastic gloves, glasses, avoid splatters by partially submerging the jug before pouring, watch the fumes, 1 quart doses).
#2 - Do NOT add any calcium, alkalinity, baking soda, washing soda, hardness . . . NO MATTER WHAT ANYONE TELLS YOU.
#3 - If your pH gets too low, add a little borax. (1 box doses, added SLOWLY via the skimmer with the pump on)

Run your pump 24/7.

Lemme know when your pool is full and your pump is on.

Thank you so much!

Was he to pour 2 gal of bleach in once it is full, too?

[madwil]

yes- keep the chlorine levels normal; that will sanitize the pool at the same time the other crap is being taken care of- the chlorine shouldn't drastically affect the other stuff dissolving...

Pool has been up and running since last evening.

We put 2 gallons of bleach in this morning, chlorine is testing as not having any. Should we keep putting bleach in or can we use the saltwater chlorine generator?

Also, put 2 gallons of muriatric acid in it, Ph is now testing between 6.8 and 7.2 on the test kit, closer to 6.8. Should we go ahead and add a little borax or not yet?

If we test the total alkalinity correctly, it is 190?
