I use this monthly. My septic tank was emptied last month for the first time in 8 years. The man who emptied it could not believe it. I drop one pod in one of 4 toilets once a month and flush twice per previous owner. The previous owner said in 12 years he had never drained the tank. I highly recommend this product. I didn't have any problems. I just thought I better not push my luck any further.
