Hi James,
All our food-based products are made from natural ingredients and 0% fillers. The ingredients for our products are listed on the bottles, we do not hide this information from hobbyists.
Products such as LPS pellets contain the most nutritious blend of food available for LPS coral, it is not just a random mix of foods that will trigger a feeding response. Using this product alone will strengthen the coral's colors, polyp size, and disease resistance.
For SPS, we offer several products, Reef Vitality is one of them. RV is a unique blend of bio-polymers and food which allow corals to become more efficient in consuming food. SPS coral will utilize more of what they consume and in turn, grow faster, color up, and have improved polyp extension. This benefit also allows for nutrients to be reduced.
The effects of any product cannot be pinpointed to only product itself, many other variables come into play.
