I was thinking of trying out the tropica root tabs for my 280L. It has a straight sand substrate in anticipation for substrate dwellers and fish who filter/look through the sand for their food. I wanted to check that using these root tabs with the resin balls won't eventually be problematic if they got to the surface. (The pictures below are not my own.)

"The capsules do not fully decompose and the small balls inside the capsules will remain in the substrate after all nutrients have been released. The balls are made of resin, which is biologically harmless." |
