Automatic Liquid Bleach Dispenser

[aquarium]

I'm considering two of these, one for bleach and one for muriatic acid.



I have the Intermatic timers with the yellow disk:



Similar to that image, but two since I have a booster pump for the Polaris.

My thought was to hook the peristalic pumps for the chemicals to the Intermatic timer electric lugs for the main pool pump so they couldn't turn on unless the pool pump is running. My concern is that some bleach and acid would be squirted into an empty PVC pipe upon being energized at the beginning of the cycle. How are bleach and acid feeders normally timed?

aquarium, did you proceed any further on this idea? I too am looking for a highly reliable liquid chlorine feeder that can safely operate unattended with only weekly maintenance visits.

Not yet. I'd like to place the tank inside because of the high air temps here in the summer. But correspondence with the manufacturer indicates that it's not an airtight lid, nor is it set up to vent the tank to the outside.

I am going to rehash this old thread. Has anyone found an inexpensive, reliable way to automatically dispense small amounts of bleach into a pool? I have a 6000ish gal pool that I would estimate that I add about a cup of bleach a day to maintain. It would be nice if I could automate that process.

Weird, I was just looking at this old thread too. I think I am going to give the Haas thing a try and see how it goes. Adding bleach all the time is a PITA and I don't want to go SWG, too much money. This seems like a good compromise.

There is a European patent for using a dishwasher rinse-aid dispenser as a chlorine (or bromine) dispenser. It's evidently designed to dump it's contents over many cycles, so it could be used to dispense bleach a bit at a time.

I haven't gotten my little pump out of winter storage yet, but will probably this next week. Its just a small metering pump which works very well. When I set it back up I will take a picture. One hose goes it the bottle of bleach and the other in the skimmer, and set it as low as it will go.
