One gallon of AquaKlenz Plus is needed in the BioSystem every 30 days or less, depending on the aggressiveness of treatment.

Augmenting natural waste degrading processes reduces sludge in intensive aquaculture and generally means cleaner water throughout your system. This creates less stress on your fish, resulting in an increase in productivity and health.
With the patent pending OptiBac BioSystem, you may need less water and fewer water exchanges to maintain normal stocking densities. Your discharge water will be cleaner.

Users with up to 50 acre foot pond systems have reported reduced incidents of problem algae, using minimal amounts of AquaKlenz Plusin their OptiBac BioSystems. An aggressive biological shock treatment of a 43 acre foot lake with 8 inches of visibility resulted in "crystal clarity" in about two weeks at a cost of less than $200!
"I saved $1500 over what I would have spent on other products. In three weeks water clarity doubled to in excess of five feet. I had no visible outbreaks of algae blooms the rest of the year 2000 and the water is the clearest it has ever been."
