calcium redundancy

[ari5736]

So many of the stories that I have heard of hard coral tanks crashing have to do with alk swings due to something getting messed up. I have an acro tank that has a calcium reactor that keeps alk steady.

I try to dump kalk into my reactor every so often to raise the ph, and it doesn't affect my kh at all, being that the demand of the tank if pretty high.

So my question is, does anyone know of a system that can back up a calcium reactor's supply of calcium to the tank, in case of some sort of failure, when kalk won't get the job done.

Asidre from all the stories of tanks crashing due to calcium deficiency, I just recently had my calcium reactor stop due to the regulator not being open enough, and thank God my kalk did not dip to low before I caught it.

The fact is I can see many places that the system can fail, anywhere from solenoid problems, leak or kink in tubing, CO2 running out when I am not near the tank for a couple of days, and on and on.

I can't think of anything that doesn't involve knowing there is a problem, and taking action. An alarm on your pH probe?

Maybe 2 separate calcium reactors? (talk about redundant?)

Maybe a dosing pump triggered with 2 part?

If you run a system controller, you could set an alarm to sound when either the solenoid stays on too long, or if the PH in the reactor climbs above it's set point.

This would at least alert you if the Co2 runs out or is somehow cut off.

use a co2 sensor on your ca reactor
