Tank Series - Get yourself a Python for your Tank, especially freshwater!
I love this piece of equipment...especially if you have a freshwater tank, I would HIGHLY recommend this one!! FYI, the more you turn on your sink, the more powerful suction you'll get. I didn't have AS strong because I didn't turn on the water at the sink fully. There are plenty of uses to have this piece of equipment in your arsenal!
