    How do you measure bleach?

    New to BBB and so far, it's working great. My question - when the calculator tells you how much to add, do you measure it out accurately, or do you "guesstimate"? Should I get a measuring cup and do it right? Thanks!

    I use a graduated gallon container from Wally-World and measure it pretty close. I don't worry about getting it perfect, pretty close is good enough for me.

    Re: How do you measure bleach?

    I guesstimate with bleach. I use 182oz jugs of 6% bleach, and I typically shoot for the nearest 1/4 jug or so and always a little on the heavy side. Even if I overshoot by a whole 1/4 jug, it is only ~1ppm in my 17,500 gallon pool. No biggie.

    It is more important to measure with other chemicals...especially ones that don't get used up, such as calcium and cyanuric acid.

    I also use a one gallon plastic pitcher. I like it because i don't get the "glug... glug ...splash" that you can sometimes get if you pour too fast out of a gallon jug and it's more accurate.

    Re: How do you measure bleach?

    Bleach I use the 1/4 jug guess system. For LC, which I use more often, I have to pour from 5 gal. container. I have a plastic pitcher marked for 1 ppm and .5 ppm FC. Kinda makes PoolCalculator unnecessary for FC (although I used it for drawing the lines). Since my LC is 12%, the same lines work for bleach, if you divide by two.

    Measure in a Gatorade bottle. Small pool, works out great.

    Re: How do you measure bleach?

    Same here. I have a graduated pitcher for liquids and a small food scale for dry chemicals. If Pool Calc tells me to add 8.8 ozs of something....I'm right there.

    Re: How do you measure bleach?

    You can only get so close with the calculated additions anyway. There will always be inaccuracies in the estimated volume of the pool, and some leeway in the CYA results, so the recommendations of the calculator are good, but only as good as the accuracy of all of the input numbers. There is nothing wrong with measuring, and I've done my fair share of it, but the only sure way to know the outcome of what you're adding is to use your test kit to measure it after it's added to know for sure what it did.

    Ultimately, you develop a feel for what your pool needs and you don't have to measure so accurately, you'll just "know".

    Re: How do you measure bleach?

    Being that I'm new to maintaining my own pool and haven't quite gotten the 'bug' for extreme accuracy, so here's how I'm doing it.

    For me, simplicity is the key. I need to be able to eyeball it. I purchase those 2.5 gallon yellow chlorine jugs from the store. Each one of those is 320 oz which equals 80 oz x 4. I won't even bother adding chlorine to my pool unless it needs at least 1/4 jug, or 80 oz. Then, I'll only add chlorine rounded up to the nearest 1/4 jug. This way, it's fairly easy to eyball it and even if I'm over/off by a 1/4 jug, it won't have too much affect on things. Again, simplicity is key for me.

    Also, I live in South Florida and have a LOT of evaporation and rain. This keeps things changing fast enough where being off by a 1/4 jug here or there wont have any lasting effects.

    I hope I don't get slammed for what I just wrote.

    Re: How do you measure bleach?

    Thanks for the replies. That pretty much tracks with what I've been doing; i.e. guessing to the nearest 1/4 gallon, maybe a little on the high side. I'll post my numbers tomorrow and maybe someone can verify that I'm on the right track. Great site; I'm learning a lot here!

    Re: How do you measure bleach?

    I round up to the nearest quart then eyeball it on the side of the jug.

    I use a measuring cup for the acid, I usually round up to the nearest 1/2 cup. But even that is inexact, I don't hold it up and peer at the meniscus.

    I have a measuring bucket that measures up to 64 ounces that I use. Picked them up at walmart for a few bucks each. I have one for bleach and one for acid and they work great.
