Calcium Reactor question?

I may be wrong on this but I don't think you do, unless it gets mushy on you, all you should have to do is add more as it dissolves.

 

It just dissolves away so in my case I am always just adding more.

With that being said I crank mine on super high and the media lasts about 2-3 months easy.

 

Calcium Reactors don't function as 'filters'. The crushed coral is the calcium that is being added over time. It's an additive, like a Ph balancer, buffer, or food. You don't really replace the food in your tank. Once its added its added. Likewise, the calcium reactor should be taking your crushed coral into a liquid form, making the liquid into a slightly less acidic form then tossing it in the tank.

I think the trick is to think of the crushed coral not as a media but as an additive.

 

Ahhhh.. i see the problem now. There may be an obstruction within the tubing if a large piece of coral got lodged in or there might simply be build up of calcification. But I would think that the acidic water would crumble that away easily.
