Sand Waterfall Questions
I am planning to build a waterfall sand aquarium but I am stuck with the size of sand. I want to get a sand where it doesn't make the aquarium cloudy and the air pump will push the sand up. I have been looking at eBay to get a quartz sand but I am stuck with the size. The medium size is 0.6 - 1.18mm and the fine size is 0.25 to 0.60.
