Aylad,

I'm thinking 182 oz is not enough I'm thinking I need another gallon to get to your estimate of 2.6 correct??Should be 277 oz. Even though I'm now using bleach and the test kit isn't all that accurate I did add 7 bags of the hth super shock over a 2 week period so not sure what else is in that besides chlorine I'll have to check the bags to see if there's any cya in that. Thoughts??

Those bags of shock were probably dichlor and if so, they do have CYA in them.

This link to a bleach calculator we use may be helpful to you. It is more than just a bleach calculator, though. If you click in the upper left corner, it gives you lots more.

1 gallon = 128 ounces. 2.6 gallons = 332.8 ounces. 2.6 gallons of 6% bleach is what will raise chlorine 13K gallons of water by 12 ppm. I'm not sure I'm understanding your first line of the above post?

You'll have to check the ingredient label on the super shock--if it's cal-hypo, it's not stabilized. If it's dichlor, then it has CYA--enough that for every 10 ppm of chlorine it adds, it also adds 9 ppm of stabilizer.

Ok Guys, The super shock I put in is cal hypochlorine and doesn't list anything but says 48% other ingredients. Probably no cya since my test never lost the black dot. It says it balances, sanitizes, shocks and destroys organics. Based on Aylads calculation and the fact that the pool is still light green the 182 oz jug is short if I add 2 tonight I'll have 364 oz so shouldn't raise it too much above the 12ppm. Your range was 12-15 anyway.

I was unable to get the distilled water so I have to use my hth 6 way test. After about an hour after I put in the 182 jug I get no reading so I know I'm above 5-10 the highest level on my test. In the morning I test and the level then drops to the 5-10 .I retest at 6pm when I get home and have zero so taking a day and a half basically to loose the chlorine.

Nothing is dusting up when I brush .The pool is a light green today after the 182 jug last night and it rained all night too. The stabilizer should be here tomorrow I'll add 4lbs. How much bleach after once I get the cya up?I'll test and post what I think the answer is so I can check myself too. Thanks

The amount of bleach you add to get to a particular point won't change, but the base amount of chlorine you'll have to keep in the pool will change once you get above 30 ppm CYA. See the "best guess chlorine chart" linked in Watermom's sig above for that info...
