Let's face it, there's no other company in the world that I would trust more than Tropica to create a product that grows plants better than anyone else. I mean, you only have to look at their plants to know about their attention to detail and quality. Others might come close but they are the leaders.
So let me introduce to you the new Tropica Aquarium Soil in both normal and powder grain size. This substrate is designed to be used on its own, no topping is required and nothing needs to go underneath it. Simply place on the bottom of your tank, and then plant directly into it, then fill with water. Easy as A,B,C.

And one more thing. The powder type is more suitable for smaller foreground plants as the grain size is better at anchoring them down and stops them from floating to the surface.
In terms of how much you need, 1 x 9L bag is suitable for 60L of water.
So all in all, I'm very excited about this substrate and know why even though it's new in to us has already sold well.
