Product Info

Mechanically dredging wastewater lagoons and ponds is an expensive process that stirs up nutrients that are trapped in the anaerobic layer of sludge and puts them into the water column to fuel algae growth. Aquafix is dedicated to providing the best biological and biochemical technology to remove wastewater sludge. This in turn saves wastewater departments and cities thousands of dollars.

VitaStim Sludge Reducer is part of a proactive approach to lagoon treatment that promotes healthy biological activity in both the indigenous and added bacteria. These gram-negative cultures set to work in every area of lagoon health to balance the biological BOD-degrading processes. This reduces compacted sludge, clarifies the water, and reduces odors. VitaStim Sludge Reducer is used in the transition times between extreme seasons, containing bacteria that are highly active in temperatures between 65-78° F.

Product Pairings

OxyPaks XL is a granular oxygen source and sludge digestion accelerator that really kicks the bacteria into overdrive to chew up sludge. It frees up sludge from the anaerobic layer to allow bacteria to easily access and digest the sludge BOD.

For extreme sludge removal, use Sludge Rx. This revolutionary tablet will turn 1 foot of nutrient-filled sludge into a few inches of bacterial biomass while dramatically reducing nutrients.

Applications and Benefits

  • Lagoon system
  • Pond system
  • Municipal WWTP
  • Industrial WWTP
  • Removes 30%-60% of sludge
  • Degrades muck and dead organics
  • Lowers ammonia
  • Heavily degrades BOD and TSS

Case Studies

48 Acre Lagoon System



A three lagoon system  in central Illinois receiving 25,000 gpd was getting bad odors every spring during “turnover.”  Turnover is when the water warms in the spring, lifting the compact sludge up.  Their large lagoons were about 6ft deep with around 2ft of sludge.  They have no aeration but enough wind action to give it white caps.  They need to minimize the sludge buildup, but like every city they were on a budget.  Hank, the public works director, began with skepticism, but that quickly turned around as his lagoons did.


They began adding 1 lbs a day of VitaStim Sludge Reducer per cell (VitaStim Polar in the winter).


After a couple of months the odors started to subside, and within the first year they reduced 40% of sludge buildup, an equivalent to 3,000 truck loads.  They continued the treatment with another 1,000 truckload reduction the following year.  They continue to produce a superb effluent and have done a phenomenal job turning the system around.

6 Acre Lagoon System



Dave and Mike operate a pond system with one 4 acre and two 1 acre lagoons in a town noted for its famed Italian restaurants.  A manufacturer in town produces frozen dinners and their discharge is about 110°F. These high temperatures create low D.O. conditions that cause odors in the lagoon. Under further investigation, we found the industry was sending loads of cheese to Dave and Mike.


VitaStim Sludge Reducer was added daily into the lagoons and Qwik-Zyme P was metered in right at the factory’s effluent to pretreat before the lagoon system.


Qwik-Zyme P heavily broke down the proteins in the cheese making it significantly easier for the VitaStim Sludge Reducer and natural bacteria to reduce the sludge buildup.

10 Acre Lagoon System


Greg and his team have a 3 cell system, one 6 acre lagoon and two 2 acre lagoons, that were becoming inundated with sludge. The ponds were about 30 years old, not aerated, and have never been dredged or treated to remove sludge.


They began using VitaStim Sludge Reducer to add new cultures and to stimulate existing bacterial cultures.


The combination of new cultures and existing bacterial cultures produced a rapid and progressive decline in their sludge levels. During the progress Greg kept saying, “The ponds keep taking on more water, but we never had to discharge.” VitaStim Sludge Reducer worked to degrade the sludge and create more capacity. Progress of sludge removal was measured by performing sludge depth measurements prior to treatment and then again one year later.

    Love these products, use them every year

  2. Kaleb G. (Il)

    Great product, use it every year on our lagoons

  3. Tony

    I inherited a 22-acre pond that was incredibly overloaded – had enormous amounts of sludge, was in effluent violation, and odors had residents very upset, to say the least. VitaStim Lagoon Sludge Reducer really helped us degrade over 3000 truckloads of sludge and control odors. Aquafix provided excellent technical support.

  4. Dave & Mike

    We have an industry in town and their loadings can sometimes cause our pond to go black and stink. The addition of OxyFresh and VitaStim Sludge Reducer really brings the ponds back fast. We have tried other products and nothing works as well. Aquafix provides excellent technical support and honest answers. We are believers.

  5. Greg

    Our wastewater ponds were filling up with sludge and we could not afford to dredge them. In the first year of treatment, VitaStim Sludge Reducer removed 330 truckloads of sludge. We are very happy.

    I have run this pond for 10 years, after I added a few packets a week later I could see bottom of the pond. This has never been possible. I highly recommend this.
