## Description

desertcart.com: 32W Aquarium UV Light for 200-3000 Gallon, UV Pond Water Clarifier for Koi Pond, Swimming Pool, Spa, Large Fish Tank, Cold Plunge UV Light for Pond Algae Control : Patio, Lawn & Garden

Review: Does a great job killing off suspended green algae. - I had been fighting algae in my Koi pond all Spring and Summer due to a broken inline UV sterilizer. Bought this 18w UV light as a temp fix until a new/larger 55w inline unit could be delivered and installed. Placed this in my waterfall spillway and within a few days the thick pea soup algae was beginning to clear up and was killed off to the point my filters could get the upper hand. Within four days the water was again crystal clear and is now maintaining since I put this in service. Not a difficult install at all. I just placed it in a spot where it would not be visible. This light has performed amazingly at a very reasonable cost. So much so that I am now reconsidering using the 55w inline UV light. Doing an amazing job as advertised. Update: Been in the pond for about three weeks now and all algae has remained under control. One of these is a must have for any pond environment. So much so, that the inline replacement I purchased has not been needed.
Review: An Effective non chemical solution!! - The 32W Aquarium UV Light is designed to clarify pond water and improve the overall health of your koi pond. When first installed, this UV light performs admirably, effectively reducing algae and keeping the water clear, which is crucial for the well-being of your fish and plants. Over the course of time the light still remains strong and effective. **3 months later update**

### ⭐⭐⭐⭐⭐ Works great, cleared green pond within 2 days. Fairly priced, kind of big, do not put near fish
*by M***Z on August 26, 2025*

Bought the 18w UV light for my outdoor 125G fish pond. I was amazed how quick it cleared up all the green algae. I put it in the upper portion with the waterfall where the fish cannot go because it stated it can be harmful to fish if put directly in the pond . It is a bit large and did not fit in my filter/pump. I only put in on every few days overnight and it has kept the pond very clear. Prior to this purchase I was using a bunch of chemicals and they did not work too well and I was worried about fish health. I would recommend this product and suggest buying through Amazon as similar lights at PetSmart were way more expensive.
