For 12 years, BZT products continue to provide us the needed probiotic treatment both in the conventional open water exchange system, and the new trend of no or limited water exchange, bioaugmented pond management system.

Como Park Zoo and Conservatory’s Horticulture Department has been using United-Tech’s BZT Aquaculture and Waste Digester products for close to 15 years to combat algae in all of our water gardens both inside and outside with great success. With the helpful guidance of the company owner we have developed a program that allows for efficiency in the use of the products with clear water as our result. We are grateful to have a natural product that is safe for all the living things that come in contact with it.

I have been using BZT on a pond in my back yard for the past ten years. It has worked well to keep the water clear with little fuss and no harsh chemicals. I put in two tablespoons every three days. It does not affect my water plants or any of the insects, frogs or ducks that come to visit, especially my bees. I am extremely happy with the product.

Joe T.Homeowner using BZT

The application of the BZT Waste Digester has improved the water quality tremendously and cut done aeration time and cost. We now applied it in all the ponds even where water quality seem manageable we still applied it. This is because the BZT Waste Digester converts all left over feeds into useful products for the shrimp to feed on. We are now relief of bad water quality management and focusing on the expansion of the farm. We also recommend the BZT Waste Digester to any shrimp farmer 100 % without any reservation for it application. CLICK link below to read the entire testimonial.

The company has excellent customer support and has answered my emails quickly. I hope they never stop manufacturing this product. It’s powdered gold for my ponds. I have had two rock bottom ponds for 14 years. They are contiguous 3,000 and 1,000 gal and contain koi, shebunkin and comet goldfish. Highly recommended!
