Chris i think that my 612 Geo calcium reactor is not made for the large grain schuran type calcium media and i will need to back to the A.R.M reactor media that i have used for many years.

RokleM my 612 Geo calcium reactor would need more flow than the eheim 1048 pump that came with it to work well with large grain schuran type calcium media ,large amount of bubbles stay in the media and come out all at once .
