Aquarium Pharmaceuticals First Layer Pure Laterite 20oz
Product Review (submitted on June 6, 2009):
It seems to be doing it's job. Blended right in with the gravel I had. And the plants look like they are enjoying it-what plants I can see. Which leads me to the "bad" of the review. Rinse, rinse, rinse, and rinsed it again, and it STILL clouded the water. Give it a few days and it will start to subside. Great product so far, very pleased.
