D Flow Designs FLEX 34L Chamber 1 Custom Media Basket - This media basket allows you to make efficient use of your back filter chambers. It allows you to place various filter media on its different layers and forces the flow of the water to pass through each level of the basket to provide superior filtration for your reef.
This includes our Flow Director which is now attached to the top of chamber 1 for an easier install. The flow director provides better surface skimming and direct flow over your media.
