My planted tank has grown much more vibrant since switching to Bio-Stratum. The roots of my plants spread easily and the color intensity has improved noticeably. The bacteria seem to be active within a week of adding the substrate.

I used it in a 20-gallon tank with a mix of stem plants and moss. The growth was steady and the water parameters stayed stable. The granules don’t compact, which is a big plus for delicate root systems.

After a few weeks, my anubias and java ferns showed much better root development. The substrate feels light and porous, and the plants are thriving without needing extra fertilizers.
