The best bacteria for septic tanks and cesspools
Private houses and garden houses often cannot be connected to a centralized sewerage system. Then come to the rescue septic tanks, which accumulate liquid and solid waste products, organic and inorganic waste. In order to less often call vacuum trucks and prevent the formation of an unpleasant odor, fatty deposits and blockages, bacteria are used for septic tanks, the best of which we will discuss in the material.

How to choose bacteria for septic tanks

There are no universal products, for each treatment system it is necessary to select its own biological agent
When choosing a reliable biological agent for cleaning and improving the performance of home septic tanks, the following criteria are followed:
- Safety for humans, nature and the sewer system itself. The product must be non-toxic, biodegradable and will not corrode plastic and rubber pipes.
- The volume of waste to decompose or the volume of the septic tank. The more effective the product, the greater the amount of the contents of the treatment plant will be able to process
- Long term. Optimal application of a single dose of the drug 1 time in 3-4 weeks
- Versatility. The presence of both aerobic and anaerobic bacteria in the composition guarantees effective work in closed and open systems.
- Ease of use. Some of the funds are produced ready-made, while others must be diluted with water.
The products presented in the rating help fight blockages, deposits, unpleasant odors and siltation of the contents of septic tanks. When choosing the best composition, it is recommended to take into account the volume of your own septic tank, the nature of the waste and the optimal working time of the preparations.

You are comparing the same thing “sucking out of your finger” the pros and cons, because they apply to every drug.
As a minus, write down that “the product only works at temperatures above +5 degrees” when it comes to use in the sewer system. Have you ever had a minus in the pipes? They are in the room! In the septic tank, it is generally more than +10 even in severe winter due to the processes taking place in it.
The considered drugs do not cost money, although they are cheap. Of the entire range of biological products on the market, Biolatik and Bionex really work, but for some reason they did not get into your review, although they enjoy great prestige among consumers.
I used biogranules a few years ago. The assessment on the site is quite true (7). The time has come to fight the bottom sediment (drainage has silted up), the store advised the Polish "Sanex". Got it, tried it, it worked! The price is comparable to biogranules, but additional. I was pleased with the option to clean the drainage.
In my opinion, Sanex could be included in your review. As it turned out, many of us at work use it.
I have been using Russian-made DROP-U for many years. Development of Kazan University. Microbes are turning pig manure and chicken manure into high quality fertilizer!
And where is the promoted Bogatyr in your review, it’s also interesting.
Here Vladimir mentioned the Polish “SANEKS” in his review, and so for ten years now I have been using it not only in my septic tank, but also in my parents’ cesspool, where he not only very successfully fights siltation, but also the formation of dry crusts. And, most importantly, we have long forgotten about the sewers. And what else do you need!
I, too, have been “sitting” on Sanex since the beginning of the 2000s. In all this time, I haven't tried anything yet. I will not argue, there are very worthy drugs on the market, but they are all much more expensive than my “time-tested” (as it is written on the package) “Saneks”. And if the result is the same, why pay more? Yes, and finally bring it into consideration on the site. It is Polish, and not fakes with the same name that have appeared on sale.
I skimmed through the comments and wanted to express my opinion. In the first, Anton writes about Biolatika and Bionex that have appeared on the market. I will not argue about their real work. Most likely it is, I personally have not tried it. But why should we forget about the Biogranules (made in South Africa) and SANEX (made in Poland) that appeared back in the 90s, which have been on our market for more than 20 (!) years and have overwhelmingly positive reviews not only from those who have been using them for a long time, but also from those who buy them “on the advice of friends”.
And this year we bought a bioactivator for septic tanks from Expel. Our friends praised him directly. Means in tablets, threw it simply into the toilet, let it dissolve and flushed the water several times. This method allows you to keep the septic tank in order. Due to the tablets, the volume of waste in the septic tank is reduced, and an unpleasant odor is eliminated.
