I settled on using a small powerhead to feed the reactor from the sump and then a dripline valve on the exit side of the reactor to adjust the effluent rate. Wasn't perfect: it would tend to vary a tiny bit, some days a little higher, some days a little lower. The overall average flowrate was the basic key. If I ever did a calcium reactor again (but I wouldn't, but if I did) I would use a peristaltic pump or a metering pump set at the desired flowrate.
