King Technology Pool Frog system AND green pool

[Winicott]

Glad there is some improvement today.

By the way, I think you have overstated your volume in your signature. I also have a 27ft AG. The volume is more like 17-18K gallons. It would be a good idea to make that change. We need an accurate volume when giving chemistry advice especially.

You are right! I left out some important info.

I slope into a flat deep end that is 5' 6" or so that I think accounts for the greater volume. My geometry is not that hot. So I did some searching.

I went here to get a better answer: http://www.online-calculators.co.uk/...ndervolume.php

I figured the average radius of the deep end is 10' when you figure in the slope and the step off shelf with a depth of 1.5'. This came to about 471 cubic feet. The volume of that in gallons is about 3525.

27' pool at 4' (according to google & Watermom) is 17100. I am sure this varies depending on water level.

That puts me at about 20600 gal.

It is kind of a weird volume since I feel that I always need to go slightly over what they ask for when treating for 10k gal at a time. I suppose since it is so close I would be better off to just think of the thing as 20k gal.

By the way, I put in 1 1/4 bottle of Polyquat, not 2 bottles.

Thanks Watermom for prompting me to "get to the bottom" of this *Snicker* (I think I just made a math joke)
