Chlorine tabs w/o CYA

[CarlD]

Bleach is sodium hypochlorite mixed with brine, which is saltwater. Strongest I know of is nominal 12.5%, which, when fresh cam test as high as 14%.

I did a bit more reading and discovered 100% sodium hypochlorite is a solid, unstable and very hard to find. Guess that's out.
Wish I could find an alternative to buying gallons and gallons of bleach every week. Seems like there would be a market for CYA-free tabs if they were available.

Sure would be a market! Do you have access to fresh 12.5% at least? Even though I use very little chlorine, I use the higher concentration so I have to lug less and recycle less.

We live very close to where Champion/LC 12 is packaged and distributed so ours is usually above 12.5%. You would think they would do refillables, but don't. That would help with the recycling issue for sure!

I use refillables--5 gallon carboys. I think Buckman makes and fills them, the same company that makes Polyquat 60%. I have a bunch of older gallon jugs that were filled with 12.5% originally, and I keep them to fill from the carboys.

I use the 5-gallon refillables of bleach (Liquid Chlorine, sodium hypochlorite) as well - I'm pretty sure I get them at the same place as CarlD. I kept the last 5 jugs I bought and refill them for ease of handling. If you do find a cheap source for LC, be sure to pick up a spout and wrench when you but the first one.

[CarlD]

The spout is great. My FAVORITE wrench is the ChanneLock filter wrench. Works on the spout, and also on the quick connects and most fittings. I have a pair of them and abuse the heck out of them as they are the all-purpose pool wrenches!

I'll have to look around for a bulk bleach supplier. I'm using a gallon (8.25%) every 2 to 3 days in the summer just to maintain 3-5ppm. (CYA is at 50) Shocking the pool with bleach is going to really be a pain.
Before we re-plastered, I used the fine granual dry shock. That worked OK, but I'm trying to get away from that.

I discovered re-purposing my oil filter pliers a couple of weeks ago when I couldn't find my strap wrench and needed to tighten the quick disconnect on my filter pump inlet. They really do work great!
