API First Layer Pure Laterite Aquarium Planting Medium, 20-Ounce

Yes, the laterite must be washed as does Caribsea Flora-max (see Super Natural Flora-Max). Both have a purpose, with the laterite clay providing the silt required for Amazon Swords and others aquarium plants (Google "aquarium plants requiring laterite"). The laterite provides the fine medium required for Swords, et Al., without the mess of introducing mud into the freshwater aquarium And this medium does settle out quickly when disturbed (see my Amazon video "Adding Inconvenience to the Cleaning Task" at ).

Laterite is filthy stuff initially. I rinsed and rinsed and rinsed and rinsed until it was finally clean enough to put in the aquarium. I will not buy this item again.
