Tantrika, I have used the products from Bio-Organics, and have been very satisfied with them, and with the customer service. Don Chapman, at Bio-Organics, is very helpful with any additional questions you may have. He sent additional information to me along with the products. I also used the fish meal pellets. I have no ties to the company. I am just a very satisfied customer, and would recommend Bio-Organics and Don Chapman to anyone who was interested in those products.
