    New pool fill

    New pool is filling right now. I have my tf-100 on hand. Can I start adding to get my water correct as it fills?

    You can start adding the CYA anytime you can support the CYA away from the liner. I would add a little chlorine but wait until you get a reasonable about so you don't damage the liner. The other stuff can wait until you are full.

    Re: New pool fill

    Well you know you will need stabilizer and chlorine. You will not really know what the pH will be until the pool is full to know if it or the TA need adjusting.

    So you could try to come up with a way to let the CYA start to dissolve in the water, but you have to ensure it does not sit on the vinyl or it could be faded.

    Re: New pool fill

    Thank you for the fast response! Guess I'll wait a bit for stabilizer till I can keep it off the liner. Should be filled by Friday. But I'll try to get some chlorine in there as it fills.

    That looks like it's time to begin to add chlorine and CYA as long as you can get them in and mixed.

    Re: New pool fill

    Ok. Only water movement is from the hose. Been reading other posts. Looks like i can add chlorine and mix with a brush?
    How long should I mix?

    What's a safe way to add cya? Water is about 10-12" deep in the shallow end.

    What are you using for chlorine? If it is liquid you can pour it right in front of the hose so the current mixes it. Pour slowly, say a pencil sized stream. Liquid CYA can be added the same way. Don't over do the CYA. It won't show up immediately on your test so don't add too much at first.

    You don't want granular CYA or Chlorine to sit on your liner. You can premix in a bucket until it dissolves and pour slowly into the deep end. Brush if it isn't all dissolved. I have read where people put it in some sort of "sock" and hung it in the water away from the edges.

    If I were you I would wait and see what the pro's say about the granular CYA. I'm trying to lower mine not raise it.

    Same answer... you need some chlorine. If you used a brush after pouring it in front of the hose, that would work.

    If you placed the CYA in a sock, tied it to the pole of your broom/vacuum and then placed it so your hose flows thru the sock, that would work.

    Was just going to ask about using liquid stabilizer.
    Pool has a SWG, but until it is online, I was planning on just using bleach.

    Re: New pool fill

    You could use liquid stabilizer but it is much more expensive for the same stuff as you are making with solid and water.

    As for the SWG, treat it as a chlorine only pool until you get fully balanced initially, then move your CYA and then balance again with the SWG and LC untill you get enough SWG output and you are balanced again.

    Re: New pool fill

    My new IG pool will be filled next week. I was thinking of not adding CYA but letting it accumulate by using the 3" puck chlorinator - will that take too long to build up the CYA level to the target range?

    You can find out how much each puck will add at the bottom of the pool calc. Effects of adding chem's. Just stop using them when you get to your target level if that's your plan, which I hope it is !

    They'll add it as fast as they dissolve.

    Lil update. Pool is crystal clear.

    Fc-7.5
    Ph-7.6
    Ta-80
    Ch-80
    Cya-20

    Slammed the pool once it was full. Didn't show any loss on the oclt last night. Gonna recheck tonight/tomorrow.

    I have cya in socks by a return. It's been 2 days and about half still in a sock. Kneading it 4-5 times daily. It it normal to take so long to dissolve?

    Re: New pool fill

    I can take a while... the more flow it gets, the faster it will dissolve.

    Re: New pool fill

    It'll take awhile to dissolve, but when I'm not running the pump I just throw the CYA still in the sock inside a floater (and squeeze it every once in while, like mentioned above). Though I really like the previously mentioned idea about somehow suspending the sock and allowing the fill water to run over it.

    Re: New pool fill

    Cya coming up. Measured 50 tonight.

    Tested FC twice tonight, back to back. The numbers were slightly different by 1. Could that be due to the scoop of r-0870 being a little different?

    No. Amount of powder does not really matter ... as long as you use enough to get a nice pink color.

    Maybe it's the water measurement?
