    Newbie wanting to confirm numbers

    Hi everyone, I just gutted our poolroom and started over. Last week we put in:
    Aqualink Z4
    Pentair intelliflo 2 VST
    Purex Trition FNS Plus D.E. filter (existing)
    Pentair mastertemp 250 propane heater
    Jandy Proseries Truclear SWG
    Solar for pool

    My pool is an indoor gunite/plaster 13,500 gallons with attached spa and I used the Taylor k2005 kit to take some readings today. They are as follows

    70 degrees
    FC 3
    TC 0
    PH 8
    TA 40ppm
    CH 140ppm
    CYA 0

    based on my research on this website I believe where I need to be is:

    FC 4-6
    PH 7.5-7.8
    TA 60-80
    CH 350-450
    CYA 20-30

    Does this sound correct? Also I'm hoping to have the pool temp set to 85 in the next couple of weeks if that changes your thoughts. Any help is greatly appreciated!

    Re: Newbie wanting to confirm numbers

    Yes that looks reasonable.

    The CYA will make the pool much less harsh, even though the FC might be a little higher.

    I recommend you add the FAS-DPD Chlorine Test to your kit so you have the equivalent to the recommended K-2006.

    Re: Newbie wanting to confirm numbers

    If you have the SWCG (Jandy Proseries Truclear SWG) your CYA should really be up around 70-80. It would also be good to give a salt level reading too. It looks like it want's around 3,000 ppm from the manual I checked.

    No need to be that high for an indoor pool

    That's what I get for not paying more attention. Didn't catch the "indoor", sorry.

    Re: Newbie wanting to confirm numbers

    Thanks so much! I just got the FAS-DPD today! Should I be keeping my FC closer to the 3 range? I've read because its saltwater it should be a little higher. I want to do the best I can at maintaining my pool.

    Have you added CYA yet? Chlorine level is set based on CYA level and the Chlorine CYA Chart

    Re: Newbie wanting to confirm numbers

    I haven't added it yet but will be shooting for 20-30 cya based on that chart but it doesn't state an ideal FC level for 20-30 CYA on indoor SWG pool

    The recommended FC level for a given CYA is the same regardless if indoor or not.

    Re: Newbie wanting to confirm numbers

    Oh wait, now I realize your problem. Just use the non SWG number as a target, knowing a little lower is fine. Keep it above 2ppm say.

    How come the relevant page states that the relationship is for outdoor pools, then ?

    Also, I thought the recommended levels were based on TFP user reporting ? Doesn't most TFP users have an outdoor pool ?

    Re: Newbie wanting to confirm numbers

    Yes, most pools are outdoor. It says it is for outdoor pools because it is for outdoor pools. Sun has an impact on FC and recommended CYA levels. That is why we recommend for your indoor SWG pool to set CYA at 30 and not 70 or 80. The relationship between chlorine and CYA is chemical in nature and is not affected by indoor vs outdoor factors. My recommendation is to set CYA at 30 because the test works better at 30 than 20 because the that is the lower limit of readability. And use target FC of 4 ppm. You could use 3 if you want. But, you won't be able to tell the difference between 3 and 4 and 4 will give you a nice cushion to help prevent any issues.

    Thanks so much for your help! I used pool math to determine that i need to add:
    8.8oz muriatic acid (31.45%)
    51oz Baking soda
    335oz calcium chloride
    93oz liquid stabilizer

    my question is how do I add all these chemicals? Can I do them in the same day or should i spread it out over the week? Also is there an order in in which they should be added? Thanks!

    Re: Newbie wanting to confirm numbers

    The recommended pool chemicals article in pool school explains how to add all chemicals. If you leave about 30 minutes between each chemical addition you should be fine. The order depends on what you want to change. You can put the cya in a sock and get it dissolving and then immediately start adjusting other parameters. Like maybe a little muriatic acid to lower the pH and a little baking soda to raise the TA.
