How do you measure your chlorine

Hi All,

What do you use to measure your chlorine? I'm looking to see if anyone has a great measuring device that they love to use or have any recommendations. Or do most people just pour our of a jug and guesstimate? I use 2.5 gal containers right now and it is difficult to estimate amounts and it is hard to pour out of. I could switch to gal jugs but the 2.5 gals are cheaper to re-fill. Looking for any recommendations so I don't have to explore the stores or online for something that would be best to use.

I like the clear jugs for this reason as it's easy to see the level and simple to create a calibrated reference. With your bottles you will have to transfer to measure.

I looked around and found this guy from Walmart. I wanted a thick transparent pitcher that I wouldn't be afraid of cracking and would pour easily. I just marked on the outside with sharpie in 2 cup increments - it holds 2 quarts without spilling easily.

120,

I use the big cups they give you in a hospital.. They are big, thick and marked well...

That said, I tend to not try to be too accurate about how much I add.. Close is more than close enough most of the time.. :)

Thanks,

Jim R.

I'm going to hijack this thread and ask a similar question: what safety precautions is everyone taking with liquid chlorine? I've been wearing gloves since its 10% but maybe that's unnecessary. (I certainly wear gloves and eye protection with muriatic acid, that stuff is foul.)

There is no dosage lower than 1/2 gallon in my world so no reason to measure it out. Pool is on the larger side so 1/2 gallon will raise FC 1.6. I never have a reason to add less than that.

What? Hijack! :rant: :rant: Take alook at this thread for some general safety precautions. Pool Safety - Trouble Free Pool

What everyone elects to do when no one is looking is on them. 👌

I bought a set of plastic measuring cups (4, 2, and 1 cup) for about $10 at Amazon. I use these for chlorine or MA and I am guilty of still measuring out my chlorine. ;)

I got a glass pyrex (4 cups) because I wasn't sure about chlorine (or MA) and plastic.

Other than generally being careful and not wearing anything I don't mind splashing, nothing really. I figure even if I somehow dumped it on myself I'm right there at the pool anyway, so I could just hop in. I treat it like I would bleach for clothing, even though I'm using 10% rather than 6%.

I assumed that since it was stored/shipped in a plastic bottle, the plastic measuring cup would work OK. So far, it has worked for me. However, I didn't do very well in HS chemistry, so I don't take my word on it. :)

What I DO KNOW is that there is NO GLASS ALLOWED within 30 feet of my pool. No if, and's or but's about it!!!!!!

The paint measuring buckets sold at Lowe’s or Home Depot work well for this. I have a couple and they go up to 64 oz in 8 oz increments.

One benefit of a larger pool is you don't need to be very precise. I do either 1/2 gallon (estimated) or a full gallon by pouring directly into the pool.

NO glass near the pool!
Muriatic acid does not react with plastic. It comes in plastic bottles.
The other day I was adding some muriatic acid. I use big, cheap, plastic measuring cup. I measured out some and then started doubting what pool math told me to add, so I checked the app again. Within 15 seconds the plastic measuring cup started to smoke! It didn't do any visible damage, but now I double check my numbers before pouring :)

I wonder if this was just the fumes you were seeing. I don't know why it would do anything to the plastic cup since it's usually stored in a plastic jug. :unsure:
