If I didn’t have access to a CNC router, I probably could have done about the same thing with a drawn circle and a jig saw. It doesn’t have to be a perfect circle as you have 7/8” or so between the edge of the device and the circle that goes down into the skimmer.Nice, can you run off a few for your TFP friends?
Sounds like fun. Given your low CH water and your abundant rainfall and snow melt, it should be interesting to see how well it works at maintaining your FC. Don’t fuss about the cal-hypo, your the perfect candidate pool for that form of chlorine. Pools like mine with high CH fill water are not so easy. But someday they may figure out SWG control which will work well in high CH environments.I got a call from them as they wanted more feedback - they’re going to get me into a beta for a new version of the app that should give better numerical readings.
Also (@JoyfulNoise) they said they wanted to have me help beta test the dispenser unit. I’m assuming that will have an NDA though.
