This water conditioner provides plants with organic carbon, an essential energy source critical for photosynthesis. Its efficient supply of organic carbon allows for improved plant growth and color development. In addition, it prevents the formation of bad algae, which can occur from an excess of fertilizer in the water. This product is also safe for fish and shrimp, and can even help keep the water clear by providing nutrients for beneficial bacteria. For optimal use, add 10 ml (1 cap = 5 ml) of this product per 10 gallons. Use it alone when there is an abundance of fertilizer in the water or at the bottom, such as at the start of setting up a tank. Otherwise, it can be used in conjunction with fertilizer.
