Is your Ca reactor not producing enough

I had the effluent pH close to 6.4 and my alk/cal kept going down. Eventually I had to put three gallons of media in, and kept pH efluent at around 6.7 to maintain my alk/cal. The output is a steady stream out of a 1/4" tube and my bubble count is about 90-100 bph.

I figured after 3 months of running this thing would be stable by now but something is still not right. I measured my effluent and it's at 600ppm Ca. Not bad, but I think the drip rate is the reason why my levels are as low as they are. With a tank full of SPS and the drip rate it's current at, there is just not enought to feed the corals. I will double up of the drops/minute and increase the bubbles a tad and re-test the water in few days. Hope that the solution because I don't want to end up running a kalk reactor.
