### ⭐⭐⭐⭐⭐ A must for a healthy crystal clear aquarium
*by D***A on November 29, 2024*

I use this Aqua Ultraviolet light on my 90 gallon saltwater aquarium. It creates crystal clear water and kills all unwanted bacteria

### ⭐⭐⭐⭐⭐ Still Going Strong
*by T***O on November 22, 2024*

One year in and this bulb is still working just fine, keeping my pond water nice and clear. I highly recommend this.

### ⭐⭐⭐⭐⭐ It'll be there when you need it
*by J***6 on August 10, 2025*

Excellent replacement for exactly what I need for my tank. It's on standby probably for over a year before the other one runs out. But the original is in there and this is the original that's what I like about it.
