@CarlD: Liquid Chlorine testing

[waterbear]

One other thing to consider if you are looking at "pool store liquid chorine", if it is sold in carboys that are filled on premise then it is being delivered to the store via tanker and stored in large tanks on site (I used to work in such a store and I can tell you that there is no greater joy than refilling carboys in the middle of summer in the hot Florida sun!). One time when reordering the bulk chlorine from our supplier I asked then if it was actually stronger than 12.5% (since I had notices that FC were a bit higher then expected in some customer's pools) and they said it was closer to 17% when it left their facility to compensate for the loss of strength on storage that the 12.5% was a minimum of what the product would be.

Evan,

That sound's about right. The shop were I get my LC has a very high turnover rate (plus the sun isn't quite so intense in NJ as it is in Fl, even if we are 15 degrees hotter and 20% more humid!) so I'm not surprised that it's still in the >12.5% range when I check it. They are one of the few that makes serious $$$ on LC, but that's because they go through SO MUCH of it, pallets and pallets of carboys per week.

Carl, Is there some way you can tell me your source? I'm in western Union county and the close place closed.

, pallets and pallets of carboys per week.

Now I can't get those images out of my head...they will haunt me in my sleep.

We used to fill about 5 pallets at a time at least once a day during the week and more on weekends!!!!!!
Each pallet held 20 carboys!
Our filling station was in full sun on asphalt
The temperature in summer was usually in the high 90's with Florida humidity to match (but we did sell chlorine all year since we don't close pool here and can swim about 10 months out of the year and the other two are perfect for hot tubs)!
I ruined more shoes and work uniforms than I care to think about!

Yeah, just head west on Rt 22 to Greenbrook and look for Sun Pools on the east-bound side. Branch Brook is also selling 5 gal carboys and just recently introduced square ones to replace the ridiculous round ones (that roll when on their side). But I've never tried the Branch Brook stuff.

Just ROFL thinking about it! You'd think you'd wear old shoes and uniforms to do it!

Thanks carl, I know just where they are - worth stopping by when I'm out that way.
