    New pool need some help with chemicals

    I read through pool school and know the ABCs but I just want to be sure I've got it right. I just opened an hour ago and got the filter running. I'm about to vacuum, but when do I start adding cya? The water is mostly clear just some dirt on thebottom. It tested low everything this morning. So I add stabilizer now or start slamming with bleach? Ph.and alkalinity are also low. Thank you!

    You can start adding CYA as soon as the pump is running.

    There is no need to SLAM the pool if you just filled it and the water looks good.

    Adjust PH before adding chlorine.

    What is "low on everything"?

    We like objective numbers. Too many people overmanage the chemistry trying to match some arbitrary target. If pH is 7.2, that's good enough. It doesn't have to be exactly 7.5. pH tends to rise over time.

    Please post some test results, and let us know how you got them; what test kit or whatever.

    Also, it helps a lot if we know where you are and what equipment you have. Recommendations can change depending on whjether you have a saltwater generator, for example, or live in an area with really hard water. http://www.troublefreepool.com/conte...efore-you-post

    Re: New pool need some help with chemicals

    Sorry, I was in a rush sending that first message :/.

    First off, water is not hard here.

    I have a 21' x 4' AGP 1.5 hp pump, sand filter, NO SWG.

    I ordered the tft 100 kit hasn't come yet. Previous homeowner left 5 different test kits, 3 drip tests, 2 stick tests. I tested them All and they were all about the same with the results.

    PH 6.8
    TC 0
    TA 30-40
    CYA 0

    I put the recommended amount CYA in the sock at the return.
    That's all so far.

    Can I add the borax and baking soda at the same time?

    Thanks!

    Water is not up all the way yet. A few more inches I forgot to add that. So I can't vacuum just yet

    Work on raising the PH with borax, when it gets to 7.2 (or higher) test the TA again and see where it ended up before doing any adjusting TA.

    Since the PH test reports anything below 6.8 as 6.8, the actual PH might be much lower.

    What was the CYA level you targeted ? You need to get your FC level in range for your CYA level ASAP.
    PH is fine where it is. You can leave TA alone also. 😎

    I targeted 40 CYA I put in the recommended amount of 10% bleach about 2 hours ago and tested about 30 min ago and still no sign of CYA or FC

    Something's eating your FC. Could be algae, could be sunlight, could be ammonia. If you had CYA last year at closing and none now, Ammonia starts to look like a suspect. But without accurate test results, it's all speculation. Do any of those testers measure Combined Chlorine?

    The CYA won't register on the test for about a week, unless you sprung for the liquid stuff, which will still take a while.

    + 1 to what Richard said. The CC test results will tell us a lot. You could be dealing with an ammonia problem. If that would be the case your chlorine addition would be consumed by the ammonia very quickly. Without the TF 100 in hand you won't be able to fight it.
    We need good valid test results to point you in the right direction. 😎

    No... no CC in these testers. Anything I can do in the mean time? Add more chlorine? It recommended 90oz I put in about 85oz

    Re: New pool need some help with chemicals

    Also I'm not sure if there was any CYA in the water at closing. This is a new pool to me. I would assume so though since the water was clear

    Re: New pool need some help with chemicals

    Well, the solution for algae or ammonia is the same. More bleach. Try targeting 10 and keep checking it. It could end up being a long ordeal. This recent lengthy thread involves a pool with ammonia, starting around page 5 or so.

    I would check FC level 30 min's after you dose it. If you lose a bunch that would also be another red flag for ammonia. 😎

    Re: New pool need some help with chemicals

    I just read the thread that Richard suggested. Looked like you were spot on with your suggestion (I hope you're wrong here) . I put another dose in about 15 min ago. I will check soon and let you know! Thanks
