Need Help Please - just got my taylor 2006 testing kit...

So, wondering where I go from here? Not knowing my exact cya makes it hard to know how much stabilizer to put in. Any and all responses appreciated!!

2 oz BY WEIGHT, NOT VOLUME of stabilizer will raise the CYA by 15 ppm in 1000 gallons so multiply 2 oz by the number of 1000 gallons that are in your pool to get a 15 ppm rise in CYA. Even if you start at 30 ppm then you will only go to 45 ppm and that is still well withing range (and probably better than keeping it at 30 ppm for technical reasons). Wait a week, retest and if too low add the same amount again. I would shoot for between 40-50 ppm for starters. In your roughtly 17000 gallon pool you would add 2 lbs for just under a 15 ppm rise in CYA. Not exact but close enough for government work!

(I know your pool is 27'x52 inches which works out to 18.5K gallons BUT your pool is not filled with water to the very top so I am only calculating the water height at 48" or 4 feet which comes to just a bit over 17000 gallons and is going to be much closer to the actual amount of water in the pool so you should find that every 2 lbs of CYA will raise you pool by 15 ppm or pretty close to it!)

Thank You so much Waterbear!

Here are the charts I use to calculate dosing. Print them out and laminate them so you always have them. All you need is the table and a calculator.

The first is set up with the formula on the chart for the most common chemicals you might use:
(Pool Volume / formula number from chart) X ppm change desired = amount of chemical to add in either pounds or quarts
(Just in case your math is "rusty" do the division in parenthesis first then do the multiplication)

The second is an expanded chart of formula numbers for more pool chemicals that you plug into the formula above

The third is a method of chemically calculating the volume of a pool. You really do not need this one since circular pools are pretty easy to calculate accurately (diameter X water height x 5.9 = volume of circular pool in gallons). It is more useful with irregular shaped in ground pools.

A lot of people use The Pool Calculator

but it give too much info all at once, IMHO. I prefer to just concentrate on what chemical I am currently adjusting. Either method works.

Meanwhile, your chlorine for that level CYA should be adequate, but you need to test it, I'd say, at least twice a day until you have sufficient stabilizer to keep the UV from devouring your chlorine.

BTW, your chemicals will last longer if you test 10ml of water rather than 25ml. Each drop of the test will then measure .5 rather than .2 and you'll use less. You don't need any greater accuracy than that.

Waterbear and CarlD, thank you so much for all the valuable information. It has made having a pool so much more FUN!

[waterbear]

just wait...you will one day reach that point when you say "Do I REALLY need to test the water. It looks fine. Hand me a strip!"
That is when you know the honeymoon with your pool is finally over!

LOL... hopefully that won't be too soon!!!
