Bleach Calc

[TOPDOG]

Since there is not a Mac Version of the bleach calculator - what is the recommended amount of bleach per 1000 gallons of water? I am just settting up today with nothing in water as of yet.

Thanks

Depends on your cya (stabilizer) level. What is the volume of your pool?

Topdog: just a quickie note, you'll get a lot more help if you post a separate topic about your problem. Most folks won't see it in here, as this thread isn't really about pool setup.

Hey Michael,

Is there any way to add a feature that would calculate the amount of CYA being added via the trichlor pucks? I just refilled my pool, I know how much CYA I've added, and I know how many pucks I've used so far. If I knew how much CYA each puck is adding, I could then use the dilution calculator to determine how much water change I need to do to dilute the CYA. This by-passes the need for the clunky turbidity test for CYA.

Could you get to that, by, um, Friday?

Thanks watermom! - Pool is small Intex softsided pool With only 3693 gallons of water capacity. I was hoping to find a calculator for bleach but was striking out with a MAC. I can post any further questions to pool setup.

By the way ....Sorry I forgot to add to my post no CYA s of yet. We have very hard well water....900-940ppm and a ton of Iron...water will turm rust for about 3 weeks untill the filter gets it cleared out. I need to rinse the filter a number of times to get the rust out of the water and then planned to add CYA with a sock - I figured I couldn't add it before we got it relativly filtered due to the need to rinse the filters. So for a while we will go through lots of bleach. Thanks again for the help!

Well, there's a lot of confounding factors that will throw your accuracy off with calculating how much CYA you've got in the pool. That's why testing is the best way of determinining how much you've got in there. Over time, due to drag out, splash out and pump out, your calculated number will diverge from the actual. It may be good for a short while, but eventually it will get off. Actual testing is really the best way to go about this.

That seems to be the million dollar question.

I've looked and looked and looked, to no avail...

Okay, thanks. I know it would be a rough estimate, but it would be good to know if after so much time I would want to drain down some water to dilute.

I emailed DuPont and asked them for the information on their product, we'll see.
