    Trouble clearing up cloudy water.

    I'm helping my son try to clear up his pool water. He has a 27' above ground and the water is too cloudy to see the pool bottom. We have had it up to shock level FC or above for about a week but little or no improvement in the cloudy water. We use a TF-100 test kit and the CYA is at 40 so we...

    ph reading changes to higher reading within a minute or two

    My son is trying to get his above ground pool (about 19,000 gallon) cleared up after the winter. He just had it in shock mode for a few days and the water is looking much better compared to the "swamp" he had last week. The water is still somewhat cloudy but last night he passed the OCLT test...

    Crusty white material/buildup in ladder wells/sleeves

    Hello, Just opened the pool for the third season after having it installed. It's a vinyl 18x36 but the problem is with the ladders and the ladder "sleeves" that they slip into. The sleeves are embedded into the concrete deck and they have a crusty buildup that makes removing and installing...

    cya test with the TF-100 test kit

    I'd like to get some clarification on how to read the view tube on the cya test. As an example when looking down the view tube I often think the black dot has completely disappeared. But after a few seconds I may start to see a very slight shadow where the dot is. (like I can see it and then...

    CYA measures <20 on my TF-100 test kit.

    I just took over maintenance of my parents 20 x 40 in ground pool. It was essentially a swamp when I started last week but is getting better each day. My father had always added chlorine with stabilized "pucks" so when I started I expected to see his CYA level about 100 or higher. I was...

    OTO Chlorine Test vs FAS-DPD Chlorine Test

    I have the TF-100 test kit which has both the OTO Chlorine Test & the FAS-DPD Chlorine Test. I use the OTO test daily to monitor chlorine and PH and the FAS-DPD test about weekly or so. Lately I've noticed the OTO chlorine test reading starts to creep up 1 or 2 ppm after the sample has set a...

    Water test results of almost new pool

    We have a newly installed IG pool and I just got the test results from the first water sample. I was a little surprised to see the results are not really ideal since the water seems sparkling clear from my perspective. My test kit is the TF-100 and these are the results.... FC - Free Chlorine...
