Laterite is an excellent planting medium
for rooted plants. This can be used when starting a new aquarium or added to an
established aquarium to supply potassium, magnesium, iron and sulfur, all of
which plants readily absorb through their roots.
For new aquariums: Use 1 oz for every gallon of aquarium water. Distribute
evenly on the bottom of the aquarium. Then add about 1 inch of gravel on top of
First Layer. Mix the gravel evenly throughout First Layer. Add the remaining
gravel to the aquarium. For established aquariums: Add 1 oz for every gallon
aquarium water. Distribute First Layer evenly into aquarium gravel throughout
the aquarium. Note: First Layer may cause harmless red cloud that will clear. First
Layer should be rinsed to avoid this cloud.
