Pucks without CYA / Floating liquid chlorine dispenser

[waterbear]

Well in the case of a floating liquid dispenser the chlorine would be fully shaded inside the container and used up within a week.

I think the problem is how would a floater filled with liquid float?

ouch...suprised no one has mentioned the safety aspect of doing this. Imagine a jug of bleach with holes in it to drip the chlorine out. If it blows around and ends up sitting on a step, it will bleach the liner or plaster in that area. OK, so you say you can tether the jug to one side, away from the steps.
Well, how about when the pool is used? Or little kids using the pool. You know they will play with just about anything floating in the water. They go to lift the jug out of the water and the stream of bleach drips on their hands, hair or worse, face... is this worth it?
There's been several methods attemped at inexpensive bleach feeders. Liquidmate comes to mind. It involves a cap with multiple tubes, each representing a different flow rate ( suction rate rather) going into the pump suction. Once the gallon jug is empty, you simply replace it. Big problem is the daily monitoring of your system to ensure that your bleach jug does not run out or you will experience a suction side leak.

Gotta agree with Poolsean.
IMHO the best way to automatically introduce sodium hypoclorite into a pool is with a SWG!

[mwsmith2]

Just to muddy the water a bit, there is also some folks who use a metering pump and inject the bleach that way. I was almost going to do that, but decided I didn't want to worry about a pressurized bleach system, and I didn't have a nice cool place to store the bleach while it was being used. SWC was the easiest and safest solution.

Thanks for the input. I'd love to have a SWG but just can't justify the cost with so many other home projects in-line. For the same cost I can buy sodium hypo for 5-6 years.

[waterbear]

Yes, the initial cost is highbut you are not figuring the convience factor into that equation. IMHO it far outweighs the monitay output! (But then again, I am lazy- would rather lug a bag of salt and a jug or two of acid home 3 times a year instead of gallons and gallons and gallons of bleach evey month!

Try to find PoolLife brand Active Cleaning Caplets. They are wrapped in
plastic with openings at the ends. Our local Wal-Mart carried them until
two years ago. I found them again at a local pool shop.
