For those who run kalkreactors and calcium reactors..

[mark]

Just running a Ca reactor only but finding similiar.

I can keep the Ca around 400ppm with the reactor alone but find my alk is always on the high end (11dKH) and if my effulant rate drifts up (bubble count same) then the alk wants to spike.

Been testing my mix water lately and find IO is at 11 right out of the bucket, have been considering bringing the alk down before adding to tank to give me some more head room with the tank. That and a finer valve for the reactor effulant.
