Many homeowners turn to septic tank enzymes and additives as a way to boost performance and prevent problems. But before you head to the store, it's important to understand what these products are, how they work and whether they're necessary for your septic system.

What Are Septic Tank Enzymes, and What Do They Do?

Septic tank enzymes are natural proteins that break down organic waste in your septic tank. They work by accelerating the natural decomposition process already occurring within the tank. This process involves bacteria breaking down organic matter, such as toilet paper, food scraps and fats, oils and greases. Enzymes act as catalysts, speeding up the breakdown of complex organic molecules into simpler forms that bacteria can easily consume.

  • By assisting the bacteria in their work, enzymes can theoretically:

  • Reduce sludge buildup that can lead to system backups and drain field clogs

  • Minimize the production of unpleasant odors

  • Facilitate the decomposition process, contributing to a smoother-running septic system

How Often Should You Use Them?

How frequently you use septic tank enzymes depends on various factors, including:

  • The tank’s size and level of usage

  • The current health of your system, as enzymes may help temporarily

  • The specific instructions on the brand you purchase

Generally, manufacturer instructions recommend using enzymes every 3 to 6 months. It’s essential to follow the instructions on the product label carefully and consult a professional septic service provider if you have any concerns or questions.

It’s important to note that the U.S. Environmental Protection Agency advises caution using enzymes. This is because overuse can impact the performance of the drain fields that treat septic tank wastewater. The EPA also advises not to use products that include organic solvents or strong alkali chemicals. When used frequently, these products can damage the soil structure and groundwater around your home.

Are Septic Enzymes Helpful or Harmful to Your Septic System?

The debate around the effectiveness and potential harm of septic tank enzymes and additives has been ongoing for years. While some experts argue that these products can be beneficial in certain situations, others warn they may not be necessary or could even cause harm to your septic system.

Proponents of septic tank enzymes and additives claim that they can help break down organic waste more efficiently, reducing the need for frequent septic tank pumping and potentially extending the life of your system. They also suggest that these products can help prevent clogs and backups, which can be costly and messy to repair.

On the other hand, critics argue that septic systems are designed to function with the natural bacteria already present in human waste. They believe introducing additional enzymes and bacteria may disrupt the delicate ecosystem within the septic tank and potentially cause more harm than good.

Therefore, it's advisable to prioritize proper septic system maintenance over relying solely on enzymes. This includes:

  • Pumping your tank regularly, as this removes accumulated sludge and prevents overflows.

  • Avoiding harsh chemicals, such as bleach and drain cleaners, that can kill beneficial bacteria in your tank.

  • Using water responsibly, particularly during peak times.

What Other Kinds of Septic Treatments Are Available?

While septic tank enzymes and additives are one option for septic system maintenance, there are several other treatments available:

Bacterial Additives

These products contain live bacteria cultures that can help break down organic matter in your septic tank.

Yeast Products

Yeast-based treatments can help promote the growth of beneficial bacteria and improve overall septic system performance.

Aeration Systems

These introduce oxygen into the septic tank, encouraging the growth of aerobic bacteria that can more effectively break down waste.

Drain Field Treatments

These products help unclog and maintain the drain field, which is responsible for distributing the treated wastewater from your septic tank.

Not all septic treatments are created equal, but some may be more effective than others, depending on your unique situation. Consulting with a professional septic service provider can help you determine the best course of action for your system.

Treat Your Septic System With Care

Remember, proper septic system maintenance is crucial to avoid costly repairs and potential environmental hazards. By understanding the role of septic tank enzymes and additives, as well as other available treatments, you can make informed decisions to keep your septic system running smoothly for years to come.
