Ponds, whether commercial, decorative, or agricultural, occasionally exhibit some rather foul odors. Most pond odors are caused by hydrogen sulfide (rotten egg smell), sulfur, and ammonia. Odors are also caused by algae, such as Chara (skunkweed), as well as cyanobacteria (blue-green algae).
BZT® Aquaculture is formulated with beneficial bacteria selected for the ability to outcompete hydrogen sulfide producing microbes. Sulfur thrives in pond bottom solids (dead algae, organic matter, feces etc). BZT Aquaculture breaks down bottom solids where sulfur producing bacteria thrive, accelerating the nitrogen cycle naturally and enhancing the rate at which ammonia is converted into nitrite. Ammonia is the principle cause of odors when high stocking densities or populations of fish are present.
Lastly, removing odors caused by algae is simple: BZT Aquaculture outcompete the algae for nutrients, thus preventing it from thriving. We covered this in the following article: “Pond Algae Treatment: Target the Source, Not the symptom.”
In summary, by insuring high populations of beneficial microbes and enzymes, BZT Aquaculture can alleviate most common odor problems. If your pond or water feature exhibits undesirable odors, we can help.

Algaecides - The Quick, Dirty Method
The problem with adding algaecides or similar products is that they only kill algae. They do not treat the source of the problem, which is nutrient overload in the pond.
Pour it in, say bye bye to the nuisance. That’s the logic behind algaecides, and in that respect, they work. But what happens next? When the algae dies, it sinks to the bottom and creates a sludge. This sludge has a variety of negative issues associated with it, such as aesthetics and odors. But from an ecosystem approach, this sludge is a huge nutrient (fertilizer) source for subsequent algae growth.
Bio-Based Treatment with BZT - The Sustainable Method
A simple, ecofriendly method of pond algae treatment is to assimilate its food source before it has a chance to grow. This requires no chemicals with “Danger: Poison” labels, no permit to handle toxic substances. Instead, through the addition of BZT, one can achieve pristine water conditions and MAINTAIN them. Naturally.
BZT contains targeted, all-natural microorganisms that consume excess nutrients in the water, thus ‘starving out’ other organisms, such as algae. Over time, this battle of attrition causes the algae to die off. When it dies, it sinks, and rather than the dead material building up into yet another nutrient sludge, BZT breaks up the dead material faster, using up the nutrients more quickly.
In addition, BZT eliminates odors, oxidizes ammonia, and improves fish health by providing a cleaner, biologically balanced environment for them to thrive.
BZT Koi & Pond is designed exclusively for small, backyard-type decorative and koi ponds, while BZT Aquaculture is designed for larger bodies of water with heavier organic loads (aquaculture farms, municipal ponds, etc.).
The Importance of Custom Treatment Protocols
United-Tech offers free technical service to customers, which includes custom protocols for unique and difficult situations. Though our standard instructions tackle everyday pond situations, occasionally a pond will exhibit extreme symptoms of nutrient loading and/or other factors which may need to be addressed. Available Monday-Friday, 8-5 CST, the United-Tech Support Team is here to serve our customers.
In summary, we propose that all-natural treatment with BZT is safer, more sustainable, and more sensible than adding chemicals known to provide quick results of symptoms without targeting the cause of the algae growth. United-Tech has conquered these issues for decades in agricultural, municipal and commercial water features, as well as residential applications. It is what we do.
