I have mine gravity fed from the overflow upstairs(there is about a 10ft drop), it seems to work great and there is no pump to worry about

Long story, me and my 4 foot tall calium reactor!
I used to feed it off of a pcx-40 that returns water to my main tank one floor above. Too much pressure in the reactor and busted two 1/4 inch acylic lids! Having a needle valve on the input side of the reactor does not work well, at least never did for me. Every 2 days it would start to clog a little and change my effluent rate, drove me nuts! Having the valve on the output side resulted in a very steady effluent rate, and is what I recommend. Usually on the effluent side it will not clog because there is always low ph water passing through it. Unfortunately if it is on the output side it has the possibilty of causing too much pressure in the reactor, depending on pump and how much pressure is in the line. Eventually I just spent the dough for a used lab grade dosing pump and have never looked back.
