I am looking for two media reactors, one larger one smaller or two larger.
If its the PMs then one of the 13.5" tall and one 26" tall (or 2 large ones).
If the Geos then the larger is the 6x18 and the smaller is a 4x18.
Looking for twist off top reactors, other brands will work. Not interested in models with the little plastic screws.
