When mixing treatments with filtered water, it is best to add a small portion at a time. Shake the container while adding product in small amounts so treatments mix properly and don't clump together. If treatments clump, float the container in hot water to warm the solution inside to help the product dissolve. We recommend allowing treatments to sit overnight before adding to the aquarium.
