Thank you for using Septic Scrub. I am glad the treatment worked for you. I would probably suggest that you add one more bottle of Septic Scrub and then monitor. If you pit was full, you must have had a considerable amount of the anaerobic crust built up. An additional treatment would probably be appropriate. The pit should remain essentially empty of water. It should be able to absorb the daily amount of water which it receives. If you have any questions, please do not hesitate to call toll free at (888) 352-7226.
