BleachCalc

[cadaver]

I downloaded this app and found that I was lacking the msstdfmt.dll to run it. When I would run the dilution program it would crash and give a runtime error 713.

I got the required .dll from dll-files.com and placed it in the system32 directory. After copying the file you have to open a cmd prompt and type "regsvr32 msstdfmt.dll".

Hope this helps anyone with the same issue.

Thanks for the program! :-D

Don't forget to also check out The Pool Calculator which is available on-line, can be saved to be run off-line, and is also available as an iPhone application. It does more than BleachCalc and in some cases is more accurate (the Borates calculations are wrong in BleachCalc).

Is there a Mac Version of this available?

BleachCalc is only for Windows.

Pool Calculator is a much better choice and works on Mac.

Need an android version too please.

On Android, try Simple Pool. It gets the most positive recommendations on the forum.

This .exe file no longer works for Beach Calculator. Unless it just does not work with Windows 8.

 

[JasonLion]

Try PoolCalculator.com. It has more features and works on all versions of Windows.

Yea, I have been using that on my Mac & PC already. But Bleach Calculator I thought was more geared for Chlorine testing alone.

I clicked on the link from John's post to Chem Geek's Bleach Calc, and it downloaded, but when I try to open the .exe, I get a box that comes up saying "Unexpected error." Did I do something wrong?

I would like to determine how much liquid chlorine 12.5% to put in my pool each night to maintain FC in that 2 to 6 range, maybe bump it up to 6 each night maybe? Sounds safe... what are your thoughts?
Thanks.

The tool of choice nowadays is PoolMath. There is a link for this in the link bar above between the Forum and Rules buttons

BleachCalc was written by Michael Smith (mwsmith2). As noted in this post, it does not work in Windows 8. It also has some errors in the borates calculations.

You should use PoolMath since it is being kept up-to-date by Jason. The spreadsheet I wrote, Pool Equations, is too complicated for most users though it does give correct results for more extreme pH calculations that PoolMath is only able to estimate (such calculations are complicated). Note that you can use PoolMath offline by saving its webpage from your browser for local use.

As for the proper FC level, that depends on your CYA level as noted in the Chlorine / CYA Chart in the Pool School. I don't see anything that says 2 to 6 ppm FC so I'm not sure where you are getting that range of numbers. 2 ppm FC would be the minimum for an FC level of 20-30 ppm CYA. Is your Cyanuric Acid (CYA) level really that low? Usually for an outdoor pool exposed to sunlight the CYA is higher, typically around 50 ppm. Also, typical daily FC loss is usually around 2-3 ppm.
