Review on 🐠 Clean and Clear Aquarium Water with SILICAR Mini 5W U-V Water Clarifier – Built-in Timer & U-VC Bulb Fish Tank Cleaner-Black by Courtney Wang

This product was exactly what I needed. Thanks to the possibility of choosing different operating modes, you can apply this to tanks of different sizes. The problem stems from a small design flaw: the power button is software, not hardware. That is, when you turn off the power, the device turns off, and when the power returns, it stays off. Both of my tanks went green for no reason. Apparently we lost power for 30 seconds and the UV filter came back on, and for no reason. In order to be able to see that the device was on, there was no way of knowing that it was no longer working.
