I am thinking about putting together a homemade chlorinator using a vented 5 gallon bucket with screw on lid for easy refill. It will use gravity to supply 12.5% bleach to the side of the skimmer. I am also planning on installing a 12v solenoid that will open and close flow (inline to the skimmer); possibly even a pinch valve. It can be wired to the pump timer or if need be, another timer all together.
I was planning on using aquarium tubing for the supply line. Maybe even hard line from the solenoid to the skimmer. I would rather hit the discharge but I don't really see an issue hitting the pumps input.
Thoughts .... suggestions?
