I haven't read the thread, but did do a search for "dosing pump" and did not get a hit. So I'm curious if anyone has used a dosing pump for the peroxide. It would seem to me you would have more precise control, could just use typical 3% h2o2 and wouldn't have to refill an in tank container so often. The cost is pretty much negligible. Thoughts?
I run an A and D in my big tank and a mini in the little tank all 9% with 2 catalysts, it costs me less than a pound a week to fuel them all, no power and basically nothing really to go wrong.
If you fill them over the sink put the plug in, I forgot and sent the catalysts down the plug hole!
Twice!
