12W in Line UV Light Sterilizer for Aquarium Algae Control with 12 Watt UVC Bulb Stainless Steel Ultraviolet Clarifier Green Killing Machine Algae Remover for Pond

Resistente.

⭐⭐⭐⭐⭐ I’m really impressed with this UV light. It comes in a sturdy metal-style housing that feels durable and well-made. You can’t see the light inside, but don’t let that fool you—it’s doing its job. Hookup was simple with my existing pump and hose system, no hassle at all. I was dealing with dark green water in my pond from sun exposure, and within just a few days of using this, the water started clearing up noticeably. Now it’s crystal clear! If you’re struggling with algae or murky water, this is 100% worth it. Highly recommend for anyone fighting green water problems.

Functionality: I am on my third type of filter for a 150-gal fish pond and waterfall in my backyard. Since this is only the light and is easily installed on my pump line to the fountain (took about 10 minutes), there aren't any moving parts to break or wear out. We emptied the pond and cleaned it out before installing the light. It has been in place for 2 months now, and the water is staying clean without having to add any chemicals. This is worth the money and I would highly recommend it.

No bueno...quiero retorno

I was struggling with the water since my tanks stays outdoors! I tried water changes daily but the water would turn back to green real quick. Long story short, I wasn't able to see my fish if they were more then 3 inches away front the front glass. I bought this UV light, and first I connected it to an extra water pump I have, I saw it started to have some effect, now I have it connected directly to the outtake from my canister filter. I believe it has been 3 week and the and the water now is Crystal clear. This is this is a good product!!
