Fluval C4 -Ceramic Media vs Factory C-Nodes

[Paul1792]

I'd like to gradually switch out the factory C-Nodes in the bio media trays in my two Fluval C3's on my 38 gallon tank for ceramic media. The C-Nodes tend to "dissolve" over time and the pores tend to clog.

Specifically, I'd like to use the Fluval Bio Max Ceramic Rings (made for cannisters):

Amazon.com : Fluval Biomax Bio Rings - 500 grams/17.63 ounces : Aquarium Filter Accessories : Pet Supplies

Has anyone tried this? Are they small enough to fit into the tray like the C-Nodes do?

Any other suggestions would be appreciated.

Note: I have some Seachem Matrix and many of the "rocks" are to big in size to fit into the tray.

Thanks ... I am going to place an order for some of the Fluval ceramic rings indicated above.

BTW: I still have about a third of "jar" of Seachem Matrix and there is some of it in both my C3's, the chemical chamber of my C4 (along with 2 Purigens), and a bag of it in my AC50. Problem is the size of many of the "rocks" is just too big for the C3 tray to get maximum surface area and I had to pick out only "smaller rocks" to add to the factory C-Nodes.
