Call it Stenner for cheap-skates, because that's how I roll.
After reading almost everything in TFP about automated chlorination, I decided that the Stenner was the best overall option for us. The thing that bothered me though was the price and dimensions of the Stenner tanks. So I looked around and came up with a pretty reasonable alternative, and I'm sure others have come up with very similar setups.
One thing I have to say is that I was pretty surprised at the size and heft of the Stenner pump when it arrived. I knew the dimensions but was still picturing something smaller and lighter. This is a serious piece of machinery! The optional rain roof doesn't fit on the planned horizontal mount setup, so I zip tied some left over solar panel material to protect the unit from excessive sun and rain. You can pretty much throw anything on there, like a cut up plastic jug as long as there is space for air movement.
I found a blue 15 gallon tank at glasswatersystems.com for 50 bucks.
Everything else is very straight forward. I positioned the pump on the tank so there is no interference between the chlorine lines and filling area.
Here's the cost breakdown:
Stenner 85MPHP17 $208 Locke Well & Pump 15 gal. Polyethylene tank 48 glasswatersystems.com Woods 50015 timer 19 Home Depot Mounting hardware 6
Total - $281, which is below the $300 I was shooting for.
I plan to dispense 3 times a day, noon, 3PM, and 6PM. This leaves a 3 hour buffer at both ends for clock skewing with the pump timer which is on from 9AM to 9PM. As this is a totally chlorine-novice effort, please feel free to add any advice or constructive criticism.
