100 mm Funnel

Why does BRS recommend this?

The 100 mm Funnel is almost an essential reefing took in our eyes. It’s perfect for adding dry materials to mixing jugs when making batches of saltwater aquarium additives. Fits perfectly in our Mr. Chili Mixing Jug. With a 100 mm diameter at the top and a 25 mm opening at the bottom dry chemicals flow through the funnel without clogging or making a mess.  You will not catch us mixing 2 part solutions without a funnel on hand.
