"Needed a UV light FAST and leave it to CHEWY to have just what I needed. CHEWY is the ONLY place to get animal food, and now my pond equipment. THANK YOU CHEWY!"

— Laura

"The UV light was supposed to last up to 6 months. However, it went out before the 2 month mark, and I messaged Chewy for either a refund or to send another. I chose to get another, and that one has gone out already too!"

Bottom Line

Overall, it's a good choice, especially for smaller ponds, keeping in mind the durability issues and replacement needs.
