The GEO Universal Media Chamber (UMC) is best know for its ease of use and versatility.  The unique design of the UMC allows the user to either plumb the unit as a top down flow or a bottom up flow.  When using carbon many users find it better to use the top down flow to force the water through the carbon under slight pressure resulting in better quality water.

    I have been using GEO products for years. I have used the calcium reactors and media reactors. I just added 2 of these UMC415 to my collection of GEO gear and couldn’t be happier. They are well made in the USA and way better then anything else on the market.
