Any specific function of substrate in aquarium plants?

  • In aquariums, the substrate is the layer of dirt that goes into the bottom of the tank. Plants are planted into this substrate and they are expected to grow through it using the substrate as a sort of anchoring system. A substrate is also important for more practical reasons, such as providing a surface for the fish waste to be broken down before it is able to pollute the water.

  • The stuff I got seems to be really nice. I can't remember the brand of it but I got it on Amazon.

    I read and saw several videos saying you could use potting soil in an aquarium but I feel like that might be risky.
