Fluval Plant and Shrimp Stratum - 4 kg
Great product, worth the extra money - had sand-like substrate before but that was a mess. Restarted my fish tank (from scratch) with Fluval Stratum. Did not rinse (after reading some reviews online). Just filled up the tank and apart from some floaty bits, the water is super clear (just use some bubblewrap to not disturb the substrate). No plants just yet, or fish or shrimp but first experiences count! One 4 kg bag was enough for my 60 liter tank.
