I took a lot of time to investigate Aerostresm before I purchased the Remediator product for my home. Within a month our septic puddle started getting smaller. After 68 days the ground dried and we no longer have puddles. The little machine just sits and purrs. The septic tank no longer has a bad odor and I no longer have to worry about anyone accidently stepping into a wet mess. I did a lot of reading before I bought but this, compared to new laterals or complete system is a bargain! I bought it based on the return policy so I had nothing to lose if it didn't work. So glad I made the move!!!
