National Geographic™ Aquarium Substrate
I recently added a 5.5 gallon aquarium to my classroom. I haven't managed an aquarium in years, so I had to re-learn quite a bit. I used this brand of substrate, and it has been wonderful for my little project. I placed live plants in the aquarium, and they are growing exponentially! It is easy to clean with the gravel siphon; sometimes the siphon will suck a lot of the substrate, but the substrate does not filter through the suction. This substrate is very natural looking. My aquarium is almost euphoric; it looks so natural and beautiful!

Great coloring throughout and NOT so light that it gets sucked up into a siphon.
