Hi GeneV, thank you for your honest feedback of our Rid-X Profession Septic Tank Treatment Powder. Because we want our consumers to get the best results when using our products, we cannot stress enough the importance of reading and following label directions and precautions. Usage directions are based on laboratory tests and results. When used as direct, this product should be dosed monthly and less frequent application may reduce efficacy. Please be assured we have forwarded your comments to the appropriate teams for future planning. Thank you for reaching out! Sincerely, Your Rid-X Team!
