Ca reactor on a nano

[freezetyle]

So I currently have a nano tank 15 gallons that I am dosing regularly. I know the obvious choice for this is dosing pump, but I have had much better growth/stability using the Ca reactor and with future up grades I do not want to buy separate equipment.

On a tank that small I would feed it via 1.1ml/min pump, to combat pH swing I would have to controlled via pH in the reactor keeping it relatively high as well as have a pH probe monitoring the tank so it doesn't drop too low (night time).

Any other thoughts on how to proceed or suggestions with my current plan?
