Ahh…Well isn’t that a bugger! When I initially read I was thinking he just didn’t have a shield shield - now that I read that again it makes sense. Maybe you can provide some insight then. I’m looking for an additional option for my project,
I want to post a DIY on a couple of reef aquarium forums so people can build these dosers themselves, but I want to give them the option of using a less expensive 12v dosing pump vs the more expensive 115VAC dosing pumps. The advantage of the 12v is the PWM control. With that information, do you have any suggestions?
