The way it was explained to me, you only need one pump. Calcium reactors have two: recirculation and feed pump.

I think you need two pumps - one to feed the denitrator and the second one for recirculation just like a CA reactor. You can use one pump if you gravity feed it or tee it off your main pump. The only thing missing is a bubble counter and the co2 tank/regulator. The drip rate is slightly faster than a CA reactor. One advantage of a sulphur denitrator is that you do not have to feed it as the bacteria feeds on the nitrates/sulphur.
