I stumbled upon a pretty easy way to continuously chlorinate for up to a week very simply. My recent purchase of a Liquidator got me to thinking. If chlorine sinks, then you could submerge something right in the pool, from which chlorine would continuously enter the pool. Looking at a 96 oz jug of 6% Chlorox, I thought "why not?" I just took the cap off the chlorine bottle and chucked it in my pool. I guided it down to the bottom with my leaf net so that it landed upright. I put one in the deep area, and one in the shallow area. At two days, both were still about 2/3 full of chlorine. After a week, they had about an inch of chlorine still in the bottom. After 10 days, it was pretty much emptied of chlorine, with maybe just a tiny bit left when I dumped them out.
So- my theory is- if you know how many jugs of chlorine your pool needs every 10 days, you can just submerge that many bottles (upright) in the bottom of your pool and they will slowly, evenly, and continually release that chlorine into your pool over that time... I use about 3 bottles every 10 days, and putting three upright on the bottom of my pool kept my chlorine levels constant for almost two weeks with zero effort. I'm pretty excited about it, and thought I'd share. I'm looking forward to seeing how long the big Chlorox bottles last.
I think it works because the relatively narrow opening in the top of the chlorine jug allows for a slow exchange by diffusion. I suspect you could slow it even more by only opening the foil at the top of the chlorine jug by 1/2. You could speed it up by putting the jug in an area with more flow.
I still need to play around with this to really dial it in, so use the above as a starting point if you want to try this.
I've been lurking here most of the summer. Really enjoy the site.
