    need help - CYA dropped after heavy rain

    Cool. Thanks for everyone's feedback. I guess I'll keep testing and scrubbing 'til it passes.

    need help - CYA dropped after heavy rain

    I thought the pump was to run 24/7 during slam?

    need help - CYA dropped after heavy rain

    I've been reading a lot about "patience", which I understand. I have a question about the OCLT. The instructions say to test before the sun hits the pool - is that correct, or do I test before the sun comes up? My pool gets sunlight pretty early.

    need help - CYA dropped after heavy rain

    I must've misunderstood some of the postings. I thought the goal was to keep it at SLAM as much as possible. I've been at this for 18 days and I just can't figure out where there could be any algae. The pool is crystal clear and the filters are clean. I don't see anything coming off the...

    need help - CYA dropped after heavy rain

    Thanks for the reply. It was at waist level, but you're correct I did have it in the sun. I'll retest in the morning. Yes, I have scrubbed the skimmer, the jets, and around the tiny light. The reason I tested CYA is because my pool is in direct sunlight all day - 12 hours. I couldn't keep...

    need help - CYA dropped after heavy rain

    I'm on day 18 of my SLAM and we got 2 days of heavy rain - I drained off 3"s. Tomorrow we have another big rain coming. I've been losing chlorine too fast, so I tested CYA and it's no longer at 40 like I thought (it was actually about 35, but I rounded up). I can still see the dot when it's to...

    Help! Build up that won't come off during SLAM - what to do?

    (Reposted into new thread due to no response) I have a question about my current SLAM. I'm on Day 11 and still losing chlorine - I believe due to a build up on the walls that I just can't get off. I have manually skimmed daily and brushed the entire pool multiple times daily. (in addition to...

    What to do first?

    Thanks so much for the help. I think I have a path to get started.

    What to do first?

    Correction: SLAM: Current 0, "SLAM Target FC" = 20

    What to do first?

    One more question: The recommended SLAM level for my CYA is "20". Do I take that recommended number and input it into the Pool Math App to get the amount of chlorine I need? (SLAM: Current 0, "Target Free" = 20) Is that how I figure SLAM?

    What to do first?

    So, the SLAM process mentions getting pH in range before starting. Is that correct? I do that first before adding chlorine? How much time do I allow in between adding chemicals before I test/adjust?

    What to do first?

    I need help with next steps. (i.e., do I add chlorine first, or lower pH?) I'm new to TFP and just now learning the basics - thanks to Leslie's chlorine tablets (high CYA). I finally drained/filled my pool enough to get the CYA down from over 200+ to around 50. Now I need to know what to do...
