Boyd EnterprisesChemi-Pure Grande Elite, 46.98 oz

I but this in my new aquarium and added 6 clown fish, 6 damsel, 8 anemones, 5 feather dusters, 5 shrimps, and a star fish all at one's and 1 1/2 month later no death, every is eating and happy.... NO MORE water change!!!!!!!!!!!!!!!!!!!

Good quality product. Wish there were more specific details on rinsing the product before use. You could run this stuff under the facet for hours still have a tint to the water.

Outstanding product that helps create clean clear water for a healthy environment.
