Review on 💡 AA Aquarium Spare Bulb UV24W - Reliable Replacement for Optimum Ultraviolet Filtration by Wendy Zhao

Product works as advertised and is great at reducing algae in my 55 gallon tank. The problem is that in one year I used 4 of these bulbs. And that includes using it for just a few hours a day or a whole month continuously. This is a quick fix if you are having ick problems, the fish will start looking better after a few days. If the lightbulb had a longer lifespan, it would be a near-perfect product.
