I am going to be purchasing a dual chamber reactor. BRS has one for $65 but would need about $30 in parts to mod it to allow for individual flow control to each canister. The Spectapure is already set up for this for $90. My only concern is the Spectrapure unit doesn't "show" the cartridges like the BRS has. I like the simplicity of the cartridge design. Does anyone have the Spectrapure reactor that can tell me if it has cartridges? I just know if it's not simple to maintain I'll procrastinate. Thanks
