    Plaster isn't right - considering an acid bath. Advice appreciated!

    My pool is 1.5 years old now. I have diamond brite plaster. It has ALWAYS been streaky/splotchy (there's also a couple "drips") and has minimal Quartz exposed. My neighbor has the same plaster, but the PB did an acid bath on his. He has a LOT of Quartz exposure and it is the look I want. We both have bahama breeze, but our water color/plaster is night and day. We had the same PB, but he didn't do the acid bath on mine. He only did it on my neighbor's after he was dissatisfied with his finish. Doing the acid bath evened out the variations in color and (I believe) exposed more Quartz in his pool.
    YES, the PB should've fixed it, but I'm over dealing with him. Things didn't end so well with us. What are your thoughts on an acid bath for these reasons and do you have a guide on how to do it properly?
    BTW, I do have a spa so the water does run through the heater (if that matters).
    Thanks in advance!

    Yes, we have a guide. I'm not a fan of acid startups, but the link is below. You don't run the equipment during the procedure while the pH is still low. Doing so could and likely would destroy your heater or severely damage it.

    Thank you Patrick. Do you know the ph goal for this process?

    I don't know what the goal is, but if you use pool math at the top of the page, you can use the effects of adding chemicals to determine about what it will be based on your pool volume. Follow the guidelines in the procedure for the amount of addition and plug those numbers in for your system.

    As for the end pH is it something you are just curious about, or do you have a way to actually test it once the proper dosage is made? The pH will be below, far below what any pool kit will test for pH wise.

    Make sure you use full strength acid 31.45%, not the half strength stuff.

    Patrick....you answered my question. Trying to test the ph will be pointless as the kit won't go that low

    I'm not sure what a base demand test is. Also, my pool is already chlorinated. Does that make a difference?
