    The Pool Calculator

    The Pool Calculator is a handy web based calculator for figuring out amounts of chemicals to add, what your calcite saturation index is, and what appropriate FC levels for your CYA level are.

    The Pool Calculator

    For background you will also want to read Recommended Pool Chemicals over at Pool School.

    Hi Jason,

    Great calculator mate!

    Suggested FC Levels :

    In the Suggested FC Levels section what do the 4 textboxes mean

    SWG : 1
    Normal : 1 to 4
    Shock : 10
    Mustard Algae Shock : 12

    I may have an idea but I just need to be sure. I have an AG non-saltwater pool so i htink SWG doesn't apply to me. Does Normal mean the 'range' that is generally accespted for your FC levels to be reading ? And does Shock mean the ppm that you want to shock your pool at initiailly to kill all the algae ? If so I'm a bit confused ... If the normal range is at 1 to 4 and you shock your pool with 10 ppm, how do you get the levels for FC back down to the 1-4 range ? Hope that makes sense.

    -S

    P.S. - This calculator is a great idea. So glad you guys made it.

    SWG is the FC level you should aim for when using a salt water chlorine system.
    Normal A to B is the range that people without a SWG system should keep their pool at day to day. The lower number is the minimum, never let FC go below that level.
    Shock is the FC level you want to maintain to kill algae.
    Mustard Algae Shock is a FC level that is sometimes required to kill persistent mustard algae.

    All of these numbers depend on your current CYA level. Enter your CYA level, hit tab, and the Pool Calculator will show levels appropriate for that CYA level.

    Chlorine gets used up, both by sunlight and by things like people and pollen in the pool. Unless your CYA level is very very high the FC level will come down from shock level to normal levels in about two days.

    Re: The Pool Calculator

    I want to use the calculator to tell me how much shock to add to my pool. I inserted all of the data parameters, and it reads "17." I believe that is the ppm of FC it wants me to raise the level to. Correct? But, I do not see how many pounds of shock I should add to achieve this level.

    Re: The Pool Calculator

    First, enter the number of gallons in your pool in the orange Size row near the top. Then enter your current FC level is the Now column of the yellow FC row and your target FC level in the Goal column of the yellow FC row. Then select the kind of "shock" you are using in the popup menu to the right, it probably says "trichlor" right now. Then, just to the left of that popup, it will tell you how many oz by weight and by volume that you will need.

    Bobbyk, look here for more answers to your questions. JasonLion

    Re: The Pool Calculator

    I think you need to convert this to a version I can download for my iPhone. That would be a great app now that it's available. There are a thousand useless apps out there now, we need a few more actual useful ones...

    You could probably sell it. Alot of these apps sell through the iTunes store for a few bucks each. How many pool/iPhone owners are there?

    Here's a link for the Developer software...hint...hint...

    Great resource and much appreciated. Would be cool to have the SWG on a seperate page though not to confuse us dumb people. LOL

    Re: The Pool Calculator

    I too would like to have the pool calculator in an iPhone app.

    Right now, I have another question about the calculator. Could you add an estimate of the change in PH as well as the change in TA with addition of baking soda?

    Re: The Pool Calculator

    The iPhone version is coming "Real Soon Now". It will not be free, but I think you will find it to be an excellent value.

    How baking soda changes the pH is now included in the beta version, in the effects of adding chemicals section. Like all of the other PH calculations in that section, the results are approximate.

    Re: The Pool Calculator

    Thanks for the beta version link Jason, that's perfect. I'll be more than happy to pay for an iPhone app that is as useful as this one. Please post somewhere on the forum when it's available.

    Love the iPhone version

    Jason, the new iPhone version of the pool calculator is great. It makes testing and adjusting my water even easier. Thanks again.

    Nice job. Now I just have to make sure I don't drop the phone in the pool while I'm out there checking the water...
