I used a Peristaltic pump on my previous pool. Get the one that has the adjustable
timer. You can have it installed to come on with your filter pump.
I used a 15 gal. barrel to store the Liquid Chlorine.
The only problem I ever had was when the tank would go empty
because I forgot to fill it.
The best part of the installation is you can keep your Chlorine level
at the exact value you like because it adds Chlorine every time your
pump is running. If you run your pump when the pool is in use it will
automatically add additional Chlorine to compensate for the bather load.
I just unhooded the SWG and changed my pool from salt water to fresh water. The salt water would splash up onto the pool deck and when the water evaporates it leaves the salt behind. This salt was eating my aluminum auto cover track along with damaging my coping stones.
