Top 5 Pond Bacteria Myths

Home / Blog / Top 5 Pond Bacteria Myths

With the multitude of products available on the market, it is difficult for an end user to determine what, if any, bacteria product is best for their pond.  Couple that with some “not so honest” sales approaches, and it can be downright intimidating trying to choose.

Here at Kasco, we always strive to be straight forward and honest and help you make the best decision for your pond, even if it isn’t with one of our products.  We have compiled some of the more common Sales Myths used with various brands of bacteria and a short explanation why they are wrong.


Myth #1 – This Bacteria is cold tolerant.

While it may technically be true that the bacteria is cold tolerant, it doesn’t mean it works when it is cold.  Think of it like this, when you put a gallon of milk in your fridge, does it last longer than if you left it sitting on the counter?  The answer is obviously yes and that is because cold slows bacterial processes.  This is the only reason we can store perishable food in refrigerators and freezers.  If bacteria worked in these cold environments, it would render both of these appliances obsolete.  Kasco’s Macro-Zyme works best in temperatures above 55 degrees . . . and so do all other bacteria products.


Myth #2 – This bacteria eats muck AND takes care of nitrogen (nitrifying)

The truth is, different bacteria strains do different things.  Heterotrophic bacteria are the kind that feed on organic matter or the muck in the bottom of the pond.  Kasco’s Macro-Zyme is a blend of heterotrophic bacteria designed to aggressively attack and remove the organic material in the bottom of your pond.  Nitrifying bacteria is a completely different bacteria type and it goes after the inorganic, nitrogen in your pond.  These are two distinctly different bacteria types.


Myth #3 – This bacteria works equally well in both fresh and salt water

Just as in Myth #2, this is incorrect because there are different strains and blends of bacteria that work better in salt water vs. fresh water.  Kasco’s Macro-Zyme is designed for fresh water environments.  In brackish water, the blend will still work, but doses would need to be roughly doubled to work effectively.  If you have a salt water application, it is best to contact us and find out about a specific salt water blend of bacteria.  Again, these are two distinctly different bacteria types.


Myth #4 – All bacteria is the same

This may be the most common myth once you get by all the sales speak.  Technically speaking, there are a limited number of bacteria strains that work well in a pond environment and many of the products available are a blend of these strains.  However, the difference lies in what else is in the package.  There are binders and fillers in all bacteria products.  The key comparison is the total amount of bacteria or CFU’s per gram or per pound.  Kasco’s Macro-Zyme has a huge concentration of bacteria topping 3 BILLION CFU’s per gram of product.  That is almost 1.3 trillion per pound.  Compare this to many of the competitors that struggle to reach 1 billion CFU’s per gram and you will see why Macro-Zyme is so effective.  Kasco’s Macro-Zyme packs a punch others can’t get up from.


Myth #5 – It’s not bacteria, its Enzymes

This is nothing but marketing and buzzword use.  Enzymes are the protein that act as a catalyst in the overall reaction of the bacteria.  The bacteria are producing the enzymes to help break down the organic or inorganic matter they are designed to target.  Some companies market their bacteria product (yes it is bacteria) as enzymes because they think some customers will be turned off by the term bacteria.  In truth, the product is bacteria and those bacteria will produce the enzymes during their decomposition processes.  Kasco’s Macro-Zyme is a high concentration of bacteria that rapidly go after organic material and create the necessary enzymes in the process.


So when you are trying to decide on which bacteria is right for you pond, talk with someone you can trust to find out what you need and get realistic expectations on performance.
