I take frequent vacations up to a month at a time.
I "made" a Liquid Chlorine dispenser while I'm gone.
20 gal Rubbermaid Trash Can.
Bulkhead to attach 10' of 1/4" sprinkler tubing to the bottom of the trash can.
1 micro flow valve.
I fill it with 9 gallons of 10% liquid chlorine and 9 gallons of water mixed up and replace the cover.
It dispenses 30 drops per minute or 3 oz. per hour.
That puts in the 18 total gallons (9 gallons of the liquid chlorine) per month.
Is this too "homemade" to work?
