    Cloudy Pool

    Welcome to TFP! I'm pretty suspect that the copper level is actually 1.7 ppm, that's about 10x higher than even PoolRx would recommend. But if it is, then the water needs dumped ASAP. Sequestering that much metal is not going to go well (as you noticed) and floc is not going to remove it.

    Test kit question

    To clarify: there is no difference in the tests for manually chlorinated or SWG chlorinated pools. All of the tests in the k 2006/TF-100 work exactly the same when used to test a salt pool. The only additional thing a salt pool needs is a quality salt test.

    My reply to a thread about borates was deleted... Am I off the mark?

    I don't recall making that aside. I recall stating that some people try to say that the procedures of the forum should be adjusted based upon what they do and do not want to do, and then comparing your thought process to those people, but nowhere did I make any comment regarding your testing...

    My reply to a thread about borates was deleted... Am I off the mark?

    I didn't realize budget constraints had an effect on chemistry 🤣 Reminds me of the people who insist we give advice based on test strip readings because they don't want to spend money on a reliable test kit...

    Featured Ultra mineral control?

    Because you decided to take a sample to the pool store "for fun" and ended up getting a hard sell that got you questioning everything. You went to a salesperson for a worthless test and got a sales pitch. What part of that was fun for you? There are better ways to waste your time.

    The best compliment...

    It's my favorite compliment to get, but it used to be even better. When I first switched to TFP I switched from the Frog System (came with the house) which uses silver and tells you to maintain 0.5 ppm FC for a low chlorine experience. Switching from that to TFPC and from 0.5 ppm FC to 6+ ppm...

    Why should I transition to salt?

    Roughly how many of them follow TFPC?

    Chlorine keeps coming out of solution

    Without real test results I cannot tell you what it is. I can only point out that sodium hypochlorite coming out of solution in a pool is impossible.

    Chlorine keeps coming out of solution

    Chlorine does not come out of solution in a pool. Whatever you are seeing, it's not that.

    best chlorine tablets for my cement pool?

    You put it in filter (where it will run through the filter and hopefully catch the debris for later backwashing) or waste (where it just dumps everything to the waste line), but never put it in backwash for vacuuming. That will deposit everything in the laterals and immediate sand and allow it...

    Why add CYA explicitly?

    I get this line of thought. I often use dichlor when I need quick CYA, or trichlor when CYA is just a little low. But here's something to remember: when CYA is too low then you lose a lot of FC to sunlight during the day. Tabs might not be able to keep up depending on how you are dissolving...

    Pooli App and Total Alkalinity

    First thing's first: are you following TFPC or are you following Pooli? Are you using their products and how are you testing your water? Your logs show a 40 ppm CYA increase and a 100 ppm CH decrease over a single day, that sounds like something you'd see from test strips... You can't mix...

    Is this algae? I think yes!

    Your comment makes no sense. One of three criteria is that your pool is free of algae, so how can you pass the and still have algae? What did you actually do?

    Is this algae? I think yes!

    Still wondering what this "24 hour algae kill" is...

    Is this algae? I think yes!

    What is that? Why?!?
