How far can i go?

[isdsms]

I want to bring my stabilizer level down in my 23000 gal inground pool. How much water can I remove before I risk problems with the vinyl liner?

I don't have a liner pool, but seems like I remember reading that you should not drain more than a third of the water. I hope someone else will step in here.... Have you tried running a search? It might take a bit of trial and error but I have no doubt the info you're seeking is in there. Good luck!

Thanks for your response. I have run a search in the "Forums" but with no success. Maybe I'll just "google it" and see what I can come up with.

With a liner pool I would not drain more than 1 foot below the skimmer or you can run into problems.

You can safely take it down to ~ 6" up the shallow end wall without worrying about having to reset the liner, actually 2" is the 'floor set' level but let's play it safe. Of course this is for a pool that doesn't have high ground water issues!

It's more efficient to drain as much water as you safely can to perform dilutions. If you suspect a ground water issue (like it's been raining for the past month, or all the local rivers are at flood stage) do multiple drainings so that you don't lower the water so much that the liner floats. Also be sure that your refill water is OK and won't cause you more problems.

Thanks to everyone for their input. I had taken the water level down to about 4" in the shallow end and started to refill today. Hopefully my cyanuric acid level will drop from its previous 100 ppm.
