Dosing

[mark]

I voted dosing though have no problems with my reactor and they can be set and forget, but a dosing pumps with a built in controller (like here) seems interesting.

Not having run them but can see dosing being about work as a reactor; initially getting dialed-in then refilling the reservoirs. Can you just mix the solutions once (or need to be re-stirred), how often to replace the tubing, life of the motors? CO2 and aragonite easy to get an really not that pricey. Dosing mixes probably not that bad if going to littlesilvermax and making your own, but if getting into the balling methods?
