Why do you need a BIG Calcium Reactor?

[urbor]

Ok so im looking into the geo calcium reactor lineup. I have never had a calcium reactor, so im kind of new to them. I just set up a 500 gallon display reef about 650 total. It will be mostly SPS. I want to get a calcium reactor but I'm a little confused on why I would need a 8x18 vs a 6x18. Is the only difference that you would just need to fill it up with media more often to keep up with your tanks demands??


Thanks

correct as you get larger calcium loads only dif is how often you will need to refill it.
