BRS Reactor Refillable Cartridge - Old Style
10” clear, refillable cartridge modified for use with Old Style BRS Reactors. Includes one clear cartridge and three foam disks (installed). This is an alternative to the newer, BRS Reactor Refillable Cartridge – Hard Shell. SKU: 204187. The newer hard shell style is more popular but either type can be used in single, deluxe and dual BRS reactors.
These are perfect for CO2 Absorption media, GFO, Carbon, and any other loose media that you want to run through a 10" reactor.
For the carbon you want to use both as you need to keep it from tumbling. On the GFO side the GFO will largely stay in the reactor cartridge on its own (and it doesn't matter if a little falls off the bottom, and gravity should keep it from going out the top) so you actually don't need to use either sponge, you can just keep those as replacements for the carbon cartridge when you need them.
