Should You Buy Septic Tank Additives?

You’ve seen the ads, “Add this to your toilet to protect your septic tank.” This may lead you to the idea that you will never have to pump out your septic tank again. It is a fantastic idea. It is so tempting to believe. But is it true?

The Short Answer

Septic systems are designed to retain human solids in the septic tank and to process out the liquid waste in a leaching field. Built-up sludge and solids that are not removed from the septic tank in a timely manner will cause problems. The image that the added bacteria will eliminate the need for your septic tank to be pumped out is not exactly accurate.

You Add More Than Human Waste

Septic systems were designed for human waste, period. Bacteria is added naturally every time you flush. But you add more to your septic tank than human waste. Two things create most septic tank problems. The addition of things not meant to be added to a septic tank or when the septic tank has waited too long to have built-up sludge removed.

When the wrong things are added to your septic tank in large amounts, you will have a problem. You will find your system having problems when too many cooking oils, kitchen grease, cleaning chemicals, laundry products or sanitary products have been flushed or poured down the drain. Some septic tank additives are designed to help.

You Need the Right Balance

Not all bacteria or enzymes can break down grease and toilet paper. Chemicals such as cleaning products will kill healthy bacteria and disrupt pH balance. When the system is disrupted, it will become overloaded. Even if you add healthy bacteria or enzymes, the moment you clean your toilet you have once again disrupted the natural balance in your tank.

Ideally, there isn’t a need for more enzymes or bacteria. Using a recommended biological additive to replenish your system’s pH, enzymes and healthy bacteria may be helpful if you have abused your system. The first sign of stress you are likely to notice is a foul odor indicating that your septic tank does not have sufficient healthy bacteria to break down your waste.

You Need to Check

Research shows that you cannot expect an overall positive effect from adding any bacteria or enzyme to your septic tank via your toilet. Doing so could damage your tank. At the same time, some products may help prolong your septic tank life. You need to check with your septic system specialist at Septic Service Pro about your septic tank’s specific needs. Call before you have a problem and extend the life of your tank.

Based on 117 reviews

Jim is a true professional who worked with me over months to identify and correct septic field problems. His positive attitude and helpful discussion in resolving issues is the best I found.


Mike and Shane came out and did an outstanding job on replacing our septic pump. Same day service - and they came out on a Friday evening! Mother's day would not have been very happy if they didn't save the day. HIGHLY RECOMMEND!!


We had our septic tank pumped and baffle tee replaced. The guys were on time, respectful and quick. They cleaned up very well after the job and even fluffed our pine straw to perfection!! We'd recommend these guys without hesitation.


Michael and Shane did an awesome job. Had to pump the septic,install a new baffle tee and tail out line. Very little yard displaced. Will definitely use Septic Service Pro again. Very pleased.


We live in Dawsonville. The crew that came out was very professional. The company owner explained to me the value and the many details about the septic that I did not know, that is why I chose them in the first place. Excellent service. R.McGary


Jim and his crew installed a new leech field for us quickly and professionally at a very reasonable cost. They handled all of the permitting and inspections and completed the work in a timely manner. Would recommend them to anyone.


Michael and assistant pointed out a leaking toilet that I didn't know I had (saved me $ there!). They also disturbed very little of the yard to get to the tank. Not the super cheapest but no hard upsell when they got here. Very pleased.


The team was efficient, friendly, knowledgeable and FAST to arrive. The bill was extremely reasonable for the work needed to be done. I would HIGHLY recommend Septic Service Pro.


These guys were amazing. Jim and Mike came when they said they would, did the job, explained everything they did. Very courteous,and professional. I am a handicapped person and felt extremely comfortable with them at my home. Thank you!!!!!
