Calcium reactor maxed out?

I have a 2 1/2 year old 150 gallon reef tank containing a variety of
SPS, LPS and fish. I have been running a Korallin Kalkreaktor model
1502 calcium reactor for nearly two years. This model is advertised
to be appropriate for a tank up to 800 gallons, so I thought it should
be more than adequate for a 150 gallon tank. Quite frankly I have not
monitored the calcium reactor regularly until the past several months
when I have obtained a varitey of SPS and a clam which of course
benefit from higher Calcium levels in the tank. It seems that no
matter how I attempt to adjust the reactor, I cannot get the calcium
level above 400. Can I assume that I am doing something wrong in
adjusting the reactor, or is calcium supplementation still required
even in tanks with a properly functioning calcium reactor. P.S. I
use ARM media from Carib-sea.

Alkalinity levels 11.5-12.5

Hi Timothy,

I have still not gotten around to using one myself, but I do know that it is
possible for the bubble counter to clog up and reduce your output, especially
after two years. I'd look at everything, including your pump, to make sure they
are all working efficiently.

Sorry to not have more practical help for you.

Marc

There is nothing wrong with Ca at 400ppm as it is the natural balance level.
Higher levels will only get things out of whack. Your levels are fine and
there is no need to make any adjustments.
