Do I need a larger Ca reactor?

[Untamed12]

I've been working for months trying to optimize the output of my Ca reactor. No matter what I try, the reactor is falling behind my usage.

I probably have close to 500 gallons of water and a 400 gallon display that is becoming fairly full of SPS.

I'm running a PM622 with 2nd stage. The reactor is 6"D x 18"H.

So....how large a reactor are some of you folks running on your systems of similar size?

GEO 1218 should take care of it for you

From what I've seen, most with the larger tanks go to bigger units with 8" chambers. I'm running a 618 successfully, but you have more gallons.

I so want that Geo 12x18!!!!!

I have a large MRC dual 10" x 24" and it doesn't even come close to the demands by my system. I supplement Kalk at night and DKH, calcium chloride during the day. These are dosed out of 50 gallon garbage cans around 4-5 cups in each. I match the 5 gallons a day evaporation, just to keep up...

You can serious under estimate the demands of a large system...
