Minnow would be controllable with the Hydros so the pH probe would tell it when to stop whereas the Jebao would be a set amount of acid each time and the pH probe would have to register how much acid went in when the pH hits 4.0. it would be doable, just easier with the Minnow.Depends on what you are dosing. Do you need 4 heads? If you need 3 heads, the jebao might make more sense. Two minnows would give you a lot of sense ports though..
I talked it over with my wife and decided I'd do the LE and Gyre, a X2 Starter with ATO pump and Solenoid, and, if the TSA is a gift card good for any purchase, probably a Minnow.
The cool thing about the Minnow is the pump can go forward an reverse so dosing live Phyto or Copepods wouldn't need a rinse cycle afterwards - dose 200 mL forward, dose 200 mL backwards. I'd have to figure out how much line to fill and how much goes into the tank.
A simple T or Y fitting with check valves and a jar of RO water would allow for a reverse rinse and a top off to the jar at the same time. Might be kinda cool, but that's down the road a bit.
