    That's as good as anything else if you can measure up to how much you need per addition with it to reach target level.

    Re: what do i need to meassure?

    i use one of the wife's old measuring cups that she never used because it was graduated in ounces instead of cups....

    you can get a decent measuring cup in the Housewares section at walmart for a couple bucks. it would be a lot easier than a baby bottle. just make sure its in ounces.

    I use a plastic measuring cup I bought at the -gasp- pool store. Unbreakable. Plus I can read the graduiations from the inside out from above, when I'm holding the acid jug far away from my face.

    I think I paid all of $1 for a plastic measuring cup from WalMart that is marked in single ounce increments up to 40oz. I can't fathom measuring out acid additions into a baby bottle...

    I vote for the plastic measuring cup from Walmart. I'm not allowed to have glass in the pool area as I am a certified clutz.......I can produce evidence of that certification.

    Re: what do i need to meassure?

    My only worry about plastic was if muriatic acid would have any issues in it. Since there are different types of plastics I wasn't sure.

    Re: what do i need to meassure?

    I use a 2 1/2 cup plastic measuring cup. I was having a hard time seeing the lines on the side so I just used a sharpie to make a mark at 10 and 20 oz. I usually add 20-25 oz. When I need 5 I just eyeball it between the 4 and 6 oz. I think I usually end up with 26 oz when I do that.

    I added a step though. I keep my bleach in the kitchen and measure it out in there so instead of trying to carry that small cup of bleach, I set it in my special bleach bucket! (It's a pretty pink bucket I got on clearance at target because I like to buy stuff.)

    If I need more than 20 oz I measure the smaller amount (usually 5 oz) dump it in the bucket then measure the 20oz and just sit the cup (full of 20 oz) in there and carry the bucket to the pool. I use the cup to pour it into the pool because it makes a nice small stream so I don't add to quickly.

    Main reason for the bucket is so I don't risk spilling the bleach on me when I'm walking out to the pool. I'm sure the one day I only need 20oz and I try to walk with that cup full I'll trip on something stupid and bleach will go everywhere!

    *edit* I've never had to use acid before so I don't know about what I'd use for that!

    4 oz of acid changes my ph by 0.04-- I don't sweat an ounce or 2. 7.4, 7.5, 7.6 so what?

    Cheap plastic measuring cup from Target for me. No issues.

    I haven't seen anyone say it, and I hope it would be obvious, but rinse that cup out really, really well with pool water in-between chemicals. You never, ever want liquid chlorine to come in contact with muriatic acid.

    Re: what do i need to meassure?

    thanks for the link....i like the idea of this jugIMG_4045_opt.jpg guess ill have to look up in pool math how much bleach gets me to 1 ppm, 2ppm and so on huh and put that on the side of a jug....guess a gallon water bottle would work btw i forgot is 4 or 5 ppm the target FC? and what happens if at some time i might be at 6 or so? im guessing its not a huge deal cause 10 and more is shock level right?

    Re: what do i need to meassure?

    I don't get why you people think in ounces (exception for DaneCE--kudos!). What a waste of time. Use ppm. I always use 12.5% LC so I use a DE scoop that is marked in ppm FC. 1 ppm FC for my size pooll is about an inch down from the top. The mark is a scratch, because LC will bleach out any known marker. MA comes in one gallon bottles. On my size pool, one-third of a bottle corresponds to one drop of acid demand reagent in the Taylor system which nobody on here uses but I prefer. Never need to calculate for FC and MA--just do it once and as long as your pool size and chem concentration doesn't change you never do it again. KISS. I save PoolCalc for my Sunday check of all chemicals.
