Product Description
Why NT-MAX Still Leads the Field

Seven decades of R & D. Developed by industry scientists and field-proven for over 70 years, NT-MAX remains the benchmark in bio-enzymatic septic care.
16,000 real five-star reviews. Independent 3rd-party ratings confirm consistent success in every U.S. climate and soil type.
Pioneer of drain-field restoration. NT-MAX introduced industrial-grade bacterial technology to homeowners and still delivers the highest colony counts on the market.
How NT-MAX Bio-Packs Protect for 28 Months
- Flush-and-forget packets – water-soluble film dissolves in seconds, releasing five billion bacteria per gram directly into the tank.
- Rapid colonization – proprietary strains double every 30 minutes, spreading from tank to drain-field lines, cesspits and pits.
- Continuous sludge digestion – enzymes liquefy fats, oils, paper and bio-mat so waste flows freely instead of compacting soil.
- Odour neutralisation – volatile acids are consumed at the source, eliminating sulfur smells without perfumes or masking agents.

Wow, NewTechBio has amazing products! I purchased the NT-Max super shock kit from NewTechBio several months ago to open up my septic system drain field after losing most of the capacity over the last seventeen years. I tried everything else on the market that I could find with little results, the contractors around the area quoted me $5000 - $8000 to replace my drain field along with the majority of my back yard would have been torn up to accomplish the new drain field. After doing much research I came across NewTechBio and thought I'd give this product one more try before replacing the drain field and I'm sure happy I did, after several months of using NT-Max super shock I have the majority of the drain field capacity back and I've been able to save myself thousands of dollars because of NewTechBio's amazing products. Thank you NewTechBio! I had to excavate my old septic system to diagnosis the failure of the leaching fields. After discovering your impressive and fast-resolving product, and "shocking" of the system, I've had excellent results. My leaching fields are dry and the tank itself isn't leaching water out of the access opening. I applied the product into the tank, and divided doses into the leaching fields. I am so excited to report that within just a week or so the tank was operating perfectly! I continue to use 1 package every month and have no problems with my septic system. Remember that my excavator quoted me saying, " this appears to be a failure due to heavy calcification in both leaching lines, and we will have to report this failure to the EPA and replace the system". Since then, we have spoken and he has been astonished with the results. I can't thank you enough for the kindness and knowledgeable staff, and especially Brad for all the helpful tips along the way, and the studies performed over the many years with excellent success.

Talked to Corey about a shortage on Order ID: 22157. The replacement product arrived three days later. Thanks to Brad for the great customer service. He handled the problem quickly and without delay. He is an asset to the company. NewTechBio was recommended by a friend who had to have both septic tank and drain field replaced. The contractor and their plumber both recommended NewTechBio as the only product to use. My system is six years old and trouble free, but after browsing your website, I felt your product would be essential for maintaining my system.

I just wanted to write and let folks know how well your product worked for us. Our septic system was in such bad shape that I was skeptical that any product would work. We did exactly as you instructed us to do and followed your directions to the letter. I was totally amazed that after a month the septic system was beginning to come around. Keep in mind that our system is very old and most likely 40/50 yrs old. So you were correct when you told me it would take a little while to start getting back to normal. The smell is completely GONE also the water has subsided and stopped coming out of the top of the tank lid. We are so grateful for your professional help and your product DOES WORK. All my neighbors love me again because the putrid smell is completely gone! I cannot stress enough how happy we are and how much money you saved us. I will advise folks that if they do not follow your instructions (to the T), they may as well just spend thousands of dollars to have a new system installed. As I said to you on the phone,"you are the septic Doctor and I will do as you suggest so my system wont die". You are a good man for helping us out and your product is simply amazing. Your professionalism is outstanding, your willingness to help is superb and second to none. Thank you, thank you, thank you!

The NT-MAX septic tank liquid shock is really great. We had problems with water and black liquid in our leachfield. We had the septic tank pumped out on Feb. 5th and today is June 3rd and our leachfield is totally dried up. I drove the lawn tractor over it for the first time this summer. Thank you very much,

After purchasing a property with a 10-year-old septic and leach field system serving both a home and an apartment, we quickly experienced persistent toilet backups and noticeable lush, green grass outlining the leach lines. Initially unfamiliar with septic systems, we tried numerous solutions, including store-bought cleaners like Drano, multiple professional and DIY line-snaking attempts, and two costly septic tank pump-outs within two years, yet issues persisted. Facing escalating problems, we nearly committed to an expensive aerobic septic system replacement, quoted at over $10,000, mandated by new county regulations. After discovering NewTechBio online and receiving helpful advice from their representative, we skeptically ordered and applied their septic shock treatment as a final attempt before converting systems. Remarkably, drainage noticeably improved in just over a month, and the previously prominent grass lines faded significantly. Three years later, the NewTechBio solution continues to perform perfectly, despite occasional missed monthly treatments. This experience has saved us over $9,500, completely eliminated septic issues, and helped avoid the burdensome maintenance our neighbors face with their aerobic systems.

As I mentioned on the phone, I had 3 separate companies inform me that I would need to replace my drainfield. Your liquid took about 7 days to completely clear up the water and the system is working perfectly now.

We just want to write and let you know how much we appreciate your help and like your products. We have been on a septic system (our first one) for 10 years. Last winter our hot tub leaked over 300 gallons of water into our leach field. We live in the Rocky Mountains and had a lot of snow all winter and were not aware of the leakage until the snow melted, plus the snow added that much more to the leach field. When Spring finally showed up to stay, we had a serious sewage swamp on top of our property. Needless to say we freaked!. We got on Google and did a search for septic systems and leach fields. We narrowed the search down to 3 companies and thankfully chose NewTechBio. Dave assured us that their products would help clean up the leach field from all of the hot tub chemicals - guaranteed - and would restore the proper amount of enzymes needed. We had to do 2 NT-MAX Shock treatments before we saw definite results. Dave generously sent us extra samples because of his confidence in their products. When the warm weather was here to stay, the leach field dried up very nicely, and we have had no more problems! We now use our plumbing normally as we did before the accident and are extremely thankful and grateful that we will not need to put in a new septic system because of NewTechBio products. Thank you, thank you, thank you!!! for your very excellent products. We also want to say thank you for your very customer-friendly service; you were always very polite and helpful whenever we called. We also appreciate the list of recommended household products you have compiled so septic users know what to buy or not to buy in order to keep our systems in good working order. We will refer your company to anyone who needs help with their septic systems and give you permission to use our name as a referral for your products and services. We are in the process of selling our house and will be sure to let the new owners know about the NewTechBio folder we have put together so they will know how to take care of this septic system, and that it is the best product on the market. Thanks again. "Success happens when preparation meets opportunity."

Wanted to let you know that we've gone a half year now without a problem in the system. Thank you for the incredible commitment which NewTechBio made to helping us get our system under control. You absolutely stand behind your product and devoted a tremendous amount of time to talking to us, to trying to determine if the specific circumstances of our system were producing unusual behavior, and then stood behind the product itself. Patty and I thank you and will recommend NewTechBio whenever the opportunity presents itself.

The shock treatment seems to work as you described. Our septic has been backing up for a couple of years now and we had it pumped 3 times since last September. We had terrible storms in April it backed up again. We pumped it again and I found you on the internet while looking for a solution. I poured the liquid right down the toilet as you suggested and that was roughly one month ago. The septic tank seems to be working fine now and every drain in the house is clog free. We have had a lot of rain this year and so far no problems. Looks good and thanks.

Dear Newtechbio team, I wish to again thank you for taking the time to assist my wife and I with addressing our septic tank concerns. Your willingness to not only bring an excellent product to the market place but to provide professional customer services and support are most appreciated. This combination of of business practices will result in our continued purchase of NewTechBio products as well as enable us to highly recommend your company to our many fellow neighbors seeking long term septic tank maintenance solutions.

Wow, all I can say is wow, I can't believe that soft spot in the yard went away. We had an area over the laterals that was wet and stinky and obviously a real problem and getting worse. We would have had to tear up the lawn and replace the leech field to solve the problem. You guys assured me that if I used your 5 gallon shock treatment and a monthly packet as directed that it would work as it had for 99% of all your other customers. You said it would take 4-6 weeks, it actually took 7 LOL but I am not in any way complaining. I just must have had a lot of gunk for it to eat through. You were right. The smell is now gone, now that the PH is back to normal we replanted grass and it looks like nothing happened. I can't believe it but it is true. You made a believer out of us. We will of course be using your product from this day forward. Thank you thank you thank you. You guys saved us a ton of money, trouble, worry and mess. I have recommended it to all my friends and as the HOA president in our area have recommended it to all our homeowners.

NewTechBio is by far, the best company I have ever dealt with. In all of the dealings I’ve had with NTB, never once was I made to feel as though they were helping because they had to. They made me feel as though they were there because they wanted to be there for any kind of help I might need. I would tell anyone with a septic system to contact the company for information about the care and feeding of that system, even if no problems exist. Had I known about NTB before my leach-line went south, I probably would not have had any problems in the first place. I cannot emphasize enough, Call these folks !! Email these folks !! if you have any kind of septic system. Their products have saved us from needing to replace our leach-line to the tune of $5000. Thanks NewTechBio- we are customers for life.

Thanks for your amazing support and advice. All we can say is that your products simply work! You saved us over $6,000.00 which we were about to fork out for a new septic drain field. I think it took about 2 weeks to get it to a very comfortable and useable result, but it was more than worth it! You have a customer for life as well as a living commercial for New Tech Bio! Please have anyone call us who needs to hear it from a very satisfied customer! < Peace I leave with you....John 14:27. Be Well,

Dear Craig, I would like to thank you for your product!! These days’ claims made by manufactures can be taken with a grain of salt. My mound system was installed around 2000 or 2001. In 2008 it was not taking effluent to the mound. After our discussion I ordered the shock treatment [5 gallon of liquid and packets] At first nothing, I called you back and you said give it awhile. So I skeptically did! Imagine to my surprise it began to work and has been working fine since. I’ve been adding 2 packets per month, one more than needed to be on the safe side. Thank you again for saving me from having to dig up the mound system, which is what I am required to have here in Northern Wisconsin.

To whom it may concern, The following is a thank you and a testimony of the product that this company is providing to the public. A brief history of my system Installed in 2002 used for 6 years as of now. My system is a 4 bedroom, the largest septic tank you can get and 4 - 50 foot drain lines it was the first time that I have been involved with as I put this home in on bare ground that had been a pasture. I had the Tank pumped and found that both sides of the tank were full . The Man who pumped the tank told me that I would probably have to replace the drain lines as they would probably be full also. At times there were as many as 9 people living in my home as some of grown children had returned home with small children The system was used to the max with a lot of washing machine use and cooking. I failed to get the system pumped until it was too late. It was discovered that I had water coming up from the lines in the front yard. I went to the local Home Depot hardware store and purchased a system treatment and used it twice in hopes to restore the system but was unsuccessful. In a last effort to save the system, I went to the internet in hopes to find some help. I went to a site named newtechbio.com I made a telephone call to the company and talked to a representative by the name of Brad. We talked for some time about my system and the problems that I was encountering. Brad recommended the products and the method of treatment and He guaranteed that their product would do the job. I was A little skeptic about this because my system was not in good shape. I was ready to try, because to replace my system would have cost me around 4 to 5 thousand dollars. 2 months later I have a system that is working fine plus I saved a lot of money. Thanks to NEWTECHBIO AND TO BRAD WHO WORKED WITH ME ON THIS PROJECT. I WILL CONTINUE USE THIS PRODUCT AND KEEP MY SYSTEM OPERATING NORMAL
