Frequently Asked Questions (FAQs)

1. Do septic tank treatments work?

There is little scientific data to suggest that you should add bacteria or enzymes to your septic system. The United States Environmental Protection Agency reported that biological additives do not appear to improve the performance of healthy septic tanks.

2. Is liquid or powder Ridex better?

The chemical is harmless to the pipes, so too much will not hurt anything. We like the powder better because it makes for a thicker liquid that goes down the drain more slowly, sticks where it's needed and seems to give a better performance. The liquid will help, but we recommend the powder version.

3. How can I increase bacteria in my septic tank naturally?

What Can You Do to Promote Septic Tank Bacteria Growth? Bacteria will grow naturally in your septic tank. You promote growth of bacteria by flushing more solid waste down into the tank all the time.
