    JUST got TF-100 HELP please

    OK, so I just received my TF-100 XL kit. I used the OTO test, 5 drops of each. The Chlorine side looked like it stayed clear & the PH looked like it was the lowest color 6.8. Do I need to do any of the other tests before trying to get the PH right. I know I am going to need to SLAM the pool as I have been fighting Algea all year so far.

    Congrats on the kit! Yes, start with getting pH right. Test for TA then use PoolMath to estimate the volume needed to raise pH to 7.4. Because your pH shows 6.8, it could actually be much lower since the test stops there. Your TA may be low as well.

    If TA is low, use washing soda or soda ash to raise both TA and pH. If TA is okay (>50), use borax to raise pH. Once you add, wait 30 minutes then retest pH. It may take a few additions to bring it up to 7.2-7.4 then start your slam! Good luck.

    Do the FAS-DPD test for FC and CC. You will need precision and accuracy before and during the SLAM.

    It is a weird one... for me anyway. Decent youtube videos out there if you need help. https://www.google.com/url?sa=t&rct=...Xx8jGp500F7S3A

    This is one test that is much easier with a speed stir, but it isn't required.

    Re: JUST got TF-100 HELP please

    So, if I am looking at this & the PoolMath right. Run to wally world & get a box of 20 Mule & add 58 OZ then wait 30 minutes & test again. Then if PH is good following SLAM directions?

    Re: JUST got TF-100 HELP please

    Assume 60. Add just over 3 lbs of borax then retest your TA. "Borax is available as 20 Mule TeamŽ Borax Natural Laundry Booster. It is sold in the laundry detergent section of most larger grocery stores and some big box stores. Borax is best added by pre-dissolving it in a bucket of water and then pouring that slowly in front of a return."

    As the others have said, while that circulates complete the rest of the test then retest pH (min. 30 minutes after borax).

    Pump on. Mix Borax in bucket of water to dissolve and pour into pool in front of return to get it circulating. And then wait 30 min and retest.

    Is Wally World Walmart? If so, stock up on 10% pool chlorinating liquid, found by the pool chemicals. Should be $2.50/bottle. Or, stock up on 8.25% bottles of bleach (unscented and not the spashless kind). I'd say grab about 8 bottles. You don't want to run out when you start SLAMing.

    Since I am above ground & Vinyl I don't really need to worry about my Calcium Hardness being 75 right?

    Leave your CYA at 35 (round up to 40 for sanity reasons). It will make the SLAM a little easier. Then you can raise to 50 when SLAM is over
