    Correct me if I'm wrong please

    So I've been pool schooling myself this morning and trying to learn, understand & operate Pool Calculator and this is what I've come up with. Please advise me of your thoughts, I'm curious if I'm going the right direction. Thank y'all

    Short version, yes.

    However, the targets are all a range because the parameters interact with each other, and the target values can be different based on pool type, type of chlorination, demographics, etc.

    They look ok to me. You have a SWG correct? Do you have one of our recommended test kits ? How did you come up with CC of 0.3 ?

    Yes my pool is has a SWG, and yes I bought the TF-100 test kit with mixer. 0.3 on CC, if above 0.5 is out of range than just figured 0.3 was a happy medium.

    Re: Correct me if I'm wrong please

    So, to be clear, the numbers you posted in your original post are not your pool test results, but just example targets?

    Can you post your latest test results for your pool? Let's get past generalizations and start looking at specifics.

    Re: Correct me if I'm wrong please

    Ill post test results as soon as I get home from work. Just curious to know how useful trichlor could be to me? I work at a chemical plant and have access to trichlor and many other chemicals, solvents, caustic. We make chlorine but its in a liquid / gas form and I'd have no way of transporting it.

    That all depends on what your current CYA level is. Unfortunately, long term use is going to be limited.

    You are referring to chlorine gas that has been compressed (liquified) and put in metal cylinders, right? I wouldn't mess with that. Is sodium hypochlorite (aka hypochlorite solutions) used or produced? It's pretty safe to transport.

    I think those numbers look great. If the water is clear, go swimming.

    Re: Correct me if I'm wrong please

    For your SWG you want your CYA level to be in the 70-80 range. Is this why you want to use the trichlor, to raise your CYA ? Is your SWG running now ?

    No I was only asking about the Trichlor because I have easy access to it. SWG has been running all day but last night I added two gal of acid and 3 lbs of turboshock step 2

    I did that because this was my test as of yesterday around noon.

    Re: Correct me if I'm wrong please

    Maybe I'm the only one confused here but....

    • 1. In order to get a pH of 7.8 after a 2 gallon acid addition, your pH would have to of been well over 9 (this is also assuming you only used 14.5% MA)


    • 2. Why the inconsistencies with CYA results? It doesn't appear you added any CYA or stabilized chlorine products. Your spike in FC seems consistent with the addition of 3lbs. of 73% cal-hypo. Can you confirm that's what the Turboshock was?


    • 3. Just a little reminder....the Chlorine/CYA chart has you shooting for a FC of 5 even though you are using dual sources for your chlorine. We're you trying to do just a miniSLAM? You can probably throttle your SWG down until you get back down to your target FC.


    Just like pwrstrk said, you wanna bump your CYA to 70. The FC dip you had is just the SWG unable to keep up. As previously discussed, you can temporarily use trichlor to chlorinate and increase your CYA simultaneously but you should set your SWG to 0% until it's need needed.

    I'm just curious if you come back...they would let you take some home? Seems very odd for a chem plant to allow that. I've been in my share of them too.

    Wow.
