You do realize, both products are made from sintered glass? Both are basically the same product, made the same way, just different shaped.Just heard about siporax biomedia from sera. It’s sintered glass so it’s chemically inert and cant leach anything, whereas people constantly complain about aluminum from marine pure blocks leaching over time as reported by ICP
