CaCo3Reef Media Reactors Review/Issues

[Cal_stir]

does the reactor flow properly without the cartridge installed?
the BRS cartridge should fit just fine, I have several cartridges and there are a couple different bottoms but the all interchange.
that type of cartridge is usually used in rodi systems which are high pressure low flow, i think the BRS media reactor cartridge is designed for low pressure high flow, so make sure you get the media reactor cartridge.
