    First set of numbers for my pool...

    Hi,
    My TF-100 kit arrived, and I have taken my first set of readings. These are the numbers:
    FC 1.0
    CC 0.5
    TC 1.5
    pH 7.8 (hard to tell this one really accurate using the kit)
    T/A 130
    CH 90
    CYA <20 (i could still barely see the dot when the tube was almost full)

    What should be my first steps here? We have a Rainbow chlorine feeder in our setup...I can use that if appropriate -- and once I figure out how I've read the Chlorine in tablet forms can do some crazy stuff to your numbers...but perhaps with the numbers I have, it would be beneficial.

    Thanks

    1. Bring your Chlorine up to around 2-4ppm and keep it there
    2. Buy some CYA and bring it up to around 40-50ppm.
    3. Do 1 and 2 simultaneously......keep an eye on your pH....it's OK for now but don't let it go any higher. (it'll get easier to do that test thru repetition.

    How does your water look?

    You'll be much happier if you leave the pucks alone.

    Re: First set of numbers for my pool...

    The rainbow chlorine feeder uses tri-chlor tabs which will lower your ph and raise your CYA. But the tri-chlor is expensive and probably not worth the expense of the minimal adjustment you need. Long term use of the tri chlor tabs will eventually cause you unwanted trouble. You would be better off just using bleach to raise your chlorine, and then buy stabilizer/CYA seperately.

    Good question. Is your water clear?

    While repetition does help get to know the test, having a verbal to go along with the visual can help, too. Here's Waterbear's interpretation of the pH color scale:

    6.8 and below yellow
    7.0 yellow with a bit of orange
    7.2-7.3 orange
    7.4-7.5 red-orange
    7.6-7.7 red
    7.8-8.0 "pinkish" or "cool" red but not quite purple
    8.2 and above purple

    So, if my test is not redish or redish orange, I'm looking at some adjusting. HTH

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

    Re: First set of numbers for my pool...

    Thanks for the responses folks. I'm going to skip the Tabs and the autofeeder.

    The water is pretty clear...maybe not quite sparkling..but it looks pretty good to me.

    When you say bring the Chlorine to 2-4ppm...whic of the Chlorine measurements is that...FC or TC?

    To increase the CYA do I just buy any bottle marked Stabilizer?
    I get these results in the Pool Calculator to increase from 20 to 40...70oz by volume.
    It also says it takes a week to fully dissolve.
    I'm thinking I should start with 35oz..and measure again in a week. Any obvious flaws in that plan?

    Thanks again

    Yep, it'll say Cyanuric Acid on the side

    I think you're on the right path

    Thanks Dave!

    Are you the one who sells the TF-100? I really like it. Brings out my inner scientist

    You're not alone in that "scientist" thing .....thanks for the compliment on the kit.

    Re: First set of numbers for my pool...

    Sorry duraleigh.... Your test kit is not complete. You need to add the following warning.


    WARNING.... Do not use this test kit infront of a klutzy, pool owning neighbor.



    I'm the one that just ordered new CYA reagent from you for my new kit.

    I just can't believe someone would test their pool's CYA so many times; get the same reading; and then retest.

    I also can't believe I loaned him the kit.
