calcium reactor media differences?

[dolt]

I am looking into getting my first ca reactor and am currently down to GEO and Deltec and the big difference seems to be media type, with the deltec using the rowalith media that is fluidized and the geo with more traditional media - is there a benefit to the fluidized media? (it is more expensive)- it makes sense to have fluidized media to have more contact between the media and CO2and to avoid channel formation but does it really make a performance difference? and can you use the rowalith media with the GEO and fluidize it in his reactor? oh yeah and one other difference is the new deltecs have screw off tops so are easier to refill
thanks in advance

I use Caribsea ARM. You only need a PH setting of 7.0.
