A coworker just bought a HUD house, hasn't closed on it yet. She doesn't know the size. I told her if she would measure the length, width and depth at deep end and shallow end, someone here could tell her approximately how many gallons? I'm assuming at this point it's a vinyl liner. She knows nothing about pools and I told her I would try to mentor her if she uses the BBB method.

I looked at picture she sent me and the water is swamp-green. I also sent her a post in this forum about a member's pool being transformed in the course of less than a week from green to sparkling blue using bleach (her realtor told her she would have to empty the pool, I told her can't do with a vinyl liner and no need to anyway).

We can't test for CYA because of the color of the water, and of course can't test the CL either until that water becomes clear, so once we know the gallonage, how in the heck do we know how much bleach to add on a twice daily basis (since she's at work during the day)?

Thanks for any help with this!
