I've not installed an injector. I haven't purchased anything to make this happen. I actually have a stenner pump I could use for the project that I used for injecting chlorine a couple years ago. After the bucket holding the Cl broke and leaked chlorine into the ground killing adjacent plants I gave up on it. I like the Pentair solution except for that stupid controller. I'd like to go that route as I suspect it'd be less problematic than a home brew solution. The concerns about problems with IC60 and the inability to inject acid in the winter give me pause.
