    Taylor K-2006 Combined Clorine and CYA level questions for Intex Ultra Frame w/SWG

    Hi,

    My setup in my Sig. Just setup the pool up last week, been about 6 days since I added 120lbs salt and 4-5 days since I added just under 1.2lbs of Cyanuric Acid per Intex 1% CYA recommendations for start (my water level is a couple inches lower).

    SWG/Pump is running 4 hours per day in between 8am-Noon.

    Taylor K-1766 Salt Test at 17 drops, 3400ppm / hth Salt Test strips show around 3000ppm. I was shooting for 3000ppm (but in Pool School I read "Salt 200-400 ppm ABOVE recommended optimum level").

    Taylor K-2006 CYA Test: 45ppm

    I did the Taylor K-2006 Chlorine Test, use 0.2ppm scale (and filled to 25ml). 28 drops = 5.6ppm FC

    After 5 drops of R-0003, the sample did not turn pink immediately. I wanted for 30-60 seconds and left. Probably 4-5 (maybe more) I came back and the sample was pink.

    I notice in a youtube video for this test, his sample immediately turned pink after adding the 5 drops of R-0003. Mine did not.

    https://www.youtube.com/watch?v=oa8iq8htR-s

    Question 1 - Do I assume my Combined Chlorine level is 0 or near (I ignore the sample turned pink after several minutes)?

    I did add the next drops after I saw it pink (after several minutes), took 3-4 drops to turn colorless, 0.6 - 0.8ppm CC - Not sure if I can or should rely on this one.

    Question 2 - For this pool and SWG setup, I should increase CYA per the Pool School's recommendation to adjust CYA to between 70 and 80 (not Intex's), is that correct?

    Question 3 - It seems like I may need to reduce the operating time of the pump/SWG to get my FC down between 3-5 (but this may depend on pool usage), is that also correct for me to assume?.

    Perhaps I should wait a two more days since I read that CYA can take up to a week to dissolve.

    Question 4 - Should I just add more Cyanuric Acid today since I'm low from the Pool School's recommendation? I'm not even sure how much more to add.

    That's all the tests I have done at this point, I want to get the Salt, CYA and Chlorine levels correct first.

    Thanks in advance - what a great forum.

    Re: Taylor K-2006 Combined Clorine and CYA level questions for Intex Ultra Frame w/SW

    Welcome to TFP!!!

    First, use 10ml of water for the FAS-DPD test so each drop is 0.5ppm ... no need for more precision.

    1. Always add the 5 drops for the CC test, if it does not turn pink immediately, then your CC is 0. It will always turn pink if you wait too long and this is meaningless. You want to do the FC and CC fairly rapidly, like a drop / second and not wait longer for the CC test any more than required to switch bottles.

    2. Yes. Protects the FC better and the SWG will not have to generate as much.

    3. Your FC level is not really that high, you may need to reduce the run time though, especially if you raise the CYA.

    4. Like you said above, the CYA may not register on the test for a week after it dissolves. No big hurry here. See how things go which your current CYA level.

    The only other level that is really important is the pH. You will have to watch it and keep it in range. The TA needs to be known, but not really something that often needs to be changed. The CH does not matter for you unless it is very high.

    If it still shows low on Sunday, then just plug your pool size and your current reading and your target CYA in and poolmath will tell you how much. Here's how to use it, explained in greater detail: http://www.troublefreepool.com/conte...ool-calculator

    Thanks guys..

    I'll recheck in a couple days, then add more CYA if necessary (which I assume will be needed).

    I'll check pH later today instead of waiting.

    I also noted in my OP that our city water is chlorinated, not fluoridated.

    Re: Taylor K-2006 Combined Clorine and CYA level questions for Intex Ultra Frame w/SW

    I went a head and did the Taylor K-2006 pH, TA and CH tests

    pH - was yellowish so I assumed low, did the Base Demand Test which required 9 drops (maybe a 10th)
    TA - 8 drops (step 4), 80ppm
    CH - 5-6 drops (step 4), 50-60ppm (maybe more purplish at 5 drops, the 6th drop was definitely blue (same color as Taylor's case).

    Questions - Did I assume correctly that the sample's pH was low (being yellowish)?

    If so, looks like I need to investigate soda ash.*

    If I need to add soda ash to raise the pH, should I wait until I get the CYA and Chrlorine levels correct or do it now?


    *I used Kem-Tek's Cyanuric Acid (99.8%) and would most likely go with their ph Plus product, is there another product I should consider over Kem-Tek's offering?

    pH is very low. You need to raise it. You can work on all the levels at once, as long as you wait 30 minutes between chemical additions. The KemTec pH plus is NaCO3; also known as Washing Soda. Absolutely the same stuff, just not packaged or priced as lavishly.

    Well, Walmart, Home Depot, Lowes (they stock Kem-Tek) and a couple pool / spa stores are around.. I don't really want more than 5lbs and don't want a bag, do like the plastic container storage...

    I can check to see what Walmart has in stock and open to what else would be recommended to raise pH. Order a lot for Amazon to but was just going to pick something up tomorrow.

    I think I will add about 1/2 pound (8oz) to start.. I don't know what the pH is now for the Pool Math, but if I enter 6.8 (for now), 7.5 goal - it states 17oz for 5000 gallons I believe.

    thank you very much

    That is right, just put in 6.8 as our now and target 7.2-7.5 or something and add the amount it tells you. Then recheck in 30 minutes to see if you are still too low and repeat the process. Never want to guess how low or high the pH is when off the scale.

    The Borax and Washing Soda come in boxes like laundry soap. Borax is also good to freshen laundry, especially smelly white socks!

    Re: Taylor K-2006 Combined Clorine and CYA level questions for Intex Ultra Frame w/SW

    Are you posting about 20 Mule Team Borax?

    I noticed in the Pool Math for my data, it says to add 17ox for Soda Ash (I would use Kem-Tek pH Up) or 34oz of 20 Mule Team Borax

    I can get 5lbs of Kem-Tek ph Up for just over $7, it seems I need 2x the qty. of Borax.. what am I missing?

    Re: Taylor K-2006 Combined Clorine and CYA level questions for Intex Ultra Frame w/SW

    I just found out we have Arm and Hammer's Washing Soda that we use in the laundry as a booster.... this appears to be the same has Kem-Tek's ph Plus for a lower price...

    From reading on the forum, it appears 20 Mule Team Borax will raise pH without changing TA, my TA is good...

    It appears I would have to use 2x 20 Mule Team Borax though there are some additional benefits apparently? http://www.troublefreepool.com/threa...ol-Why-and-How

    Which should I use (my wife will use both in the laundry)? I just want to use the recommended in our pool situation, either one's leftover can be used in laundry.

    Either. Adding that amount of borax will not add much in the way of borates.

    Re: Taylor K-2006 Combined Clorine and CYA level questions for Intex Ultra Frame w/SW

    I'm still a little confused, are you saying to add the same amount of 20 Mule Team Borax as I would add Sodium carbonate (Arm and Hammer's Washing Soda or Kem-Tek's pH Plus)?

    I did not say anything like that. Add whichever you want and the amount that PoolMath says you need.

    Does Borax = 20 Mule Team Borax?

    That is what I'm confused about now

    Yes. Borax = 20 Mule Team Borax

    Soda Ash = Arm and Hammer Washing Soda

    Both will raise pH, but by different amounts with different amounts. Make sure the correct chemical is in the drop down when you use PoolMath.

    Re: Taylor K-2006 Combined Clorine and CYA level questions for Intex Ultra Frame w/SW

    Since my TA is fine now (around 80ppm) and I'm just interested in raishing pH, should I still find and get some 31.45% Muriatic Acid to have on hand if I go the Borax option?

    From reading a few threads, it does seem to me that Borax (33oz) would be the better option as Washing Soda will also raise my TA (which is in target now).

    Sounds like I don't have to monitor the borates unless I want to optionally start down the path of getting borates to 50ppm - where I would need 31.45% Muriatic Acid and LaMotte Borate test strips.

    Is my thinking correct?

    You need muriatic acid only when you need to lower the pH. Don't worry about borates, you will have very little in the water.

    Re: Taylor K-2006 Combined Clorine and CYA level questions for Intex Ultra Frame w/SW

    Update:

    Yesterday I added a total of 32 oz of Borax (two applications of 16oz, 45 minutes apart and testing after the first).. pH at 7.6 (was 7.2 after the 1st 16oz, 7.6 after 32oz), and again 7.6 testing today. Note: Just before adding the first 16oz of Borax, tested TA and appears to have increased to 90 (though I pointed the return up to try to add Aeration earlier in the day with pump running for several hours).

    Today, added 10oz of Cyanuric Acid (using two socks, 1/2 in each near the return) - wanting to increase from 40/45ppm to 70ppm (but didn't want to add all 19/20oz from Pool Math at once).. will recheck in a few days..

    Re: Taylor K-2006 Combined Clorine and CYA level questions for Intex Ultra Frame w/SW

    Update:

    Last two days, ran the SWG for only 3 hours per day in the morning (Intex recommends 4).

    There has been no activity in the Pool yet.. may get some today.

    CYA: 55-58
    FC: 7ppm
    CC: 0ppm
    TA: 90ppm
    CH: 50ppm

    pH: Not Tested

    I took these tests about 45 minutes after the SWG ended it's daily run

    Since I'll re-do the FC test later today around 6-7PM, I'll test the pH as well at that time.

    Questions:

    I read I should take the FC test in the late afternoon/early evening, perhaps that is why my FC is elevated?

    The CYA has fully dissolved from the socks after only 2-3 days, should I still wait a full week (4-5 more days) before testing CYA and adding more Cyanuric Acid?

    Lastly, should I be concerned that my TA is at 90ppm (last two times tested, a few days apart)?
