Built one before with a pump as thought was required, but hooked up this chamber (http://www.reefcentral.com/forums/showthread.php?s=&threadid=1484033) and finding the effluent pH is 6.65, system alk 10.9dKH and Ca is 410 ppm. Drip rate is 30ml/min with 40 BPM. This is an a moderately SPS stocked 145g.

All I can see is my CO2 usage might be a little lower if hook up the pump and also do a CO2 recir.
