Josh’s Frogs Aquarium & Paludarium Sand (10 lbs)
Josh’s Frogs Aquarium and Paludarium Sand is the perfect substrate for your small aquarium, paludarium, or water feature. It’s dark, black coloration really allows fish, aquatic invertebrates, and plants to pop. It is prewashed and inert in water.
How to Use
Apply sand to the bottom of an enclosure, then slowly add water. We recommend setting a flat rock or small dish on top of the sand and pouring water on that, so that the substrate is not disturbed. Allow the enclosure to sit until the water column is clear (generally 6-12 hours), before turning on any water circulation pump.
How to Clean
Along with regular water changes, carefully use a gravel vac to remove debris from the sand. Most debris will sit on the surface of the sand.

The sand looks great in my paludarium. The dark color makes the plants stand out. I followed the instructions and waited 10 hours before adding the filter. Water cleared well and my frogs seem active now.

Easy to use and the sand holds up well after a few water changes. I used a small dish to pour water on top, which kept the sand from shifting. No issues so far.

Perfect for my small aquarium. The black color really brings out the green plants. I cleaned it with a gravel vac and found debris mostly on top, which made removal simple.
