Easy to install and fits perfectly in my small overflow box. Water flow is smooth and consistent. No leaks after a week of use. Great for small aquariums.

Works well with my 8-inch overflow box. The 1-1/4 diameter version fits snugly and maintains steady water flow. A reliable replacement for the old one.
