🐠 Enhance Your Aquarium with the Aqua Ultraviolet AAV20025 Mercury Quartz Lamp – 25-watt Review

Quartz sleeve cleaned; Installed a new bulb but still green water. tank for 500 liters; in the shade there is only one fish in the aquarium. 100 gallon pre-filter and bio-filter. I suspect the lamp is defective as it has been a few months now and the water is still green.

As soon as there is light, I mount it immediately. change the water filter every day for the first two days when the light is new. then randomly filter the water about 3/4 of the day and then once a week. the water is clear now. I can see two and a half feet
