Question: Does this dissolve completely and quickly in water? I have a fine mesh filter that this must pass through.
Document: I am a firm believer in preventative maintenance especially when it comes to the septic tank. You do not want that stuff backing up into your house. I have had very good results with Roebic septic tank and drainfield products, been using them for over 15 years and haven't had any problem.
