constant drip rate with Ca reactor?

[eli@fijireefrock.com]

You could feed it through your main pump.
it will pressurize the reactor and the valve will be adjusted accordingly.
mine been running that way for a year.

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.

started off just by tapping off my main pump to feed mine.

Nice pic. So I guess I would just drill a little hole in the PVC on the return pipe.

drill, tap and a little teflon tape...
