    trying to balance my pool

    Hello and thanks in advance for the help. I have a new pool and a seperate spa and this site has been very helpful.

    1. Can I / should I add bleach if I have a SWG and a vinyl pool?
    2. Where can I buy muriatic acid?
    3. On the pool calculator am I OK if the CSI index is under 0.6 [i am at -1.32] in a vinyl pool
    4. I need to get my CYA up - what is stabilizer?
    5. What is washing soda or soda ash and where do I get it?

    Re: trying to balance my pool

    1. Only when you have the need to shock your ppol. Otherwise the SWG provides all the chlorine

    2. Hardware store. Home Depot/Lowe's. Paint store

    3. I don't use the CSI but something is a little low. Post results for pH, TA, and CH for more help.

    4. Stabilizer is CYA (cyanuric acid) also referred to as Conditioner sometimes

    5. If you need to adjust pH (post your test results) you can do so with 20 mule team borax found readily in the grocery store. The other two are another way to do that but generally, a little bit harder to find.

    Re: trying to balance my pool

    Soda Ash and Washing soda are the same thing, pool stores call it "PH UP". Usually it's recommended when your TA is also low.

    If your TA is fine, then use Borax to raise the pH. What is your TA?

    Dave's right, post your results and we can advise better.

    Re: trying to balance my pool

    Here are my readings. I was going to add based on the Pool Calculator and after everything is balanced add the 20 Mule Team to get the borates to 50. CH 90, TA 50, Ph 7.2, Fc 0 - [I added 50# of salt this AM], CYA 20 and Borates at 0. thanks,

    Re: trying to balance my pool

    You desperately need to get some chlorine in your pool. You are begging for algae to infest your pool without chlorine.

    YOur CYA is low, YOur TA is too low, and I would suggest you disregard borates for the time being but your first and only concern should be to get some chlorine in your pool.

    At the same time you're adding chlorine, calculate enough CYA to get to 40ppm and put that in there as well.

    How does your water look?

    The water looks fine. Add the bleach to the pool and leave the pump on to circulate for a while?

    Re: trying to balance my pool

    What should i push the clorine up to? I should get stabilizer [for the CYA] at a pool supply store?

    Re: trying to balance my pool

    For now, raise the chlorine to 10ppm. Raise your TA with Baking Soda, shoot for 80 ppm. That will boost the PH very slightly and stabilize it. As you increase the CYA level, the require FC level goes up - refer to the CYA chart.

    Re: trying to balance my pool

    Bleach and baking soda are in. Do I need to go to a pool supply store for stabalizer? I will let you know how my water is tomorrow.

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

    Re: trying to balance my pool

    Yes I have thanks. Pool school clued me in on how to handle my spa and now I am getting my act together on the pool. Have a great week!
