Summer Slam

Summer Slam is a Temperature Driven Solution designed specifically for warm water applications.  This dry probiotic formula is enhanced with mesophilic microorganisms and select stimulants to ensure optimal performance when water temperatures are between 75°F-120°F (23.9°C-48.9°C).  Summer Slam will quickly cycle out excess nitrogen and temporarily bind phosphorus in warm water environments.  Made for aquatic professionals, it promotes a balanced aquatic ecosystem and rapid recovery from both adverse environmental impacts and chemical treatments.

Summer Slam excels when used alone and can be applied as a dry powder or dissolved and sprayed over the surface of the water.  For an extra boost, use Summer Slam in combination with PondZilla Pro or AquaSticker.


The Science Behind It

Water bodies have stress from both external and internal sources. Excessive rains or draught combined with ongoing use of algaecides and herbicides deplete the microbial communities that are fundamental to nutrient removal in water bodies.  This imbalance in the ecosystem leads to elevated nutrient issues and can result in excessive aquatic plant growth, continuing algal blooms, and HABs.

Summer Slam was formulated through years of research by obtaining samples from lakes and ponds across the United States when water temperatures were warmer.  The natural microbial communities in the samples were analyzed to understand population densities and the specific organisms that are depleted by stresses.  This research is how Naturalake BioSciences was able to create a probiotic that supplements natural populations and supports indigenous organisms that are functional and native to that geography.  Summer Slam is more than simple additions of beneficial bacteria.  It is a scientifically formulated probiotic that works in harmony with the microbial communities that play key roles in nitrogen and phosphorus uptake.  Real science.  Real Results.

This Ohio pond had a hydrodictyon problem and had not looked good in years. With aeration and PondZilla Black blended with an algaecide/herbicide, along with our Summer Slam and MD Pellets, the applicator cleaned up this pond like never before. Rather than just killing the hydrodictyon we focused on disrupting its life cycle.

Available Sizes
