My Geo CaReactor is maintaining my Ca, but my Alk is not stable at all. I keep having to use buffer to raise it, but it only stays raised for a few days and then slowly starts dropping. Any ideas?

You want to increase the alk of the effluent or increase the amount of effluent while maintaining the same Ph in the reactor.
To do that :
You'll want to use some combination of increasing the flow rate of the effluent and the dosing of CO2. I'd start first with the effluent flow, and see where you get. You can check the alkalinity of the effluent by measuring it directly, which will give you an idea of what your adjustment did. Give at least 12 hrs after each adjustment before measuring, as it takes time to propagate through the system. Usually an effluent alkalinity in the neighborhood of 20-40 dKH works well in most tanks. By adjusting effluent flow or CO2 dosing higher, you'll speed up the delivery of dissolved calcium and alkalinity to the tank, raising both.
I would not worry so much about the calcium level as I would the alkalinity.
