New Pool Owner, No Chlorine less than 24 hours after shocking.

Poolcalculator.com is telling me more like 55oz by volume of cal hypo. (Pool at 22,000 gallons, FC at .5, goal 15). What am I doing wrong there?

You're not doing anything wrong, I mis-typed the volume of the pool. Sorry. Correction is 68 oz by weight of 65% cal-hypo, or 80 oz by weight of dichlor. Personally, I use bleach and strongly recommend it, especially when trying to clear up a problem.

Cal-Hypo's FINE since you CH level is 200ppm. Other than adding calcium it has the fewest side effects of powdered chlorine compounds. I don't use it much because I always have Liquid Chlorine around (Just really strong bleach--12.5%--but "Liquid Chlorine" sounds so pro...It actually works out to be the same as if I was paying $1.45/gallon of 6% bleach, so I use it. But it's the same stuff).

Using Dichlor or Tri-chlor tabs is only appropriate when you need to add stabilizer and your pH is fairly high, because both (especially Tri-chlor) drive pH down and both add lots of stabilizer.

The B-B-B method is really a philosophy of easy and sensible pool care. You can do EVERYTHING with Bleach, Borax, and Baking Soda, and just augment it with Muriatic Acid and CYA powder. You don't need ANYTHING else to run a clean sanitary pool, year after year. Oh: You DO need two more things: 1) Knowledge 2) a really good test kit.

Everything else is just for convenience.

Well there we go, added approximately 3.6 x 182oz (662oz) of 6% bleach, should be at or greater than 15ppm at this point. I erred on the high side since I didn't have anything to measure with and don't know my exact pool volume yet, maybe I put in 3.7 jugs?

Will test tomorrow morning, and if I have time I'll post the results first thing.

THANK YOU to all of you who have trudged through this thread and assisted me!

90 minutes after shocking last night, I used the OTO test and dilution method and thought it should be a hair darker, so I added in the rest of my 4th jug of bleach (728oz total added last night). (Figure my pool might really be 25,000 gallons, haven't done the math yet, need to get on that. Plus we had a lot of rain last week, and despite backflushing, I'm still a couple inches high, right at the top of the skimmer).

This morning, once again using dilution and OTO, chlorine is somewhere between 9 and 15. Water still looks nice and clear. Going to work now, I'll measure when I get home.

It's working!

Got home and checked chlorine today. Used cheap OTO, diluted 50% with Brita water, and still had stronger yellow color than the 5ppm the test max's out at - so chlorine is over 10ppm.

So I think things are rolling along nicely... I think other questions I have should probably go in different threads.

Thanks for all the help!
