What is the normal daily evaporation amounts when using a 150 watt Metal Halide light? I've been losing about a half gallon every day! Is this normal? And should I be topping off with salt water or fresh (RO/DI only) water?
The bulb is about 6-6.5 inches from the surface of the water, and the hood of the aquarium has been removed (as the light is a clip on). The light is on timer and operates 9 hours each day. I also have a double-action cooling fan blowing between the light and water surface.
