9. Can Alken Clear-Flo® 1000 line products control weeds?
Since aquatic weeds do not feed from the water column, instead absorbing their nutrients directly from the sludge layer, they are not as immediately affected. Alken Clear-Flo® 1005 can be used to break down up to 90% of the organic sludge layer over six months to a year, depending on the depth of the sludge and its proportion to the water depth, with the added benefit of eventually reducing water weeds.
10. What kind of pollutants does Clear-Flo® target?
Virtually all organic contaminants except PCBs can be degraded with Clear-Flo®. These include but are not limited to: sludge, manure, grease, oil, chlorides, ammonia, nitrite, sulfide, some pesticides, hydrocarbons, cyanide and phenols.
11. How does Alken Clear-Flo® clarify the water?
Alken Clear-Flo® reduces the Total Suspended Solids (TSS) that cloud the water column by digesting the floating organic matter.

12. How does Alken Clear-Flo® deal with phosphorus in the water body?
Alken Clear-Flo® bacteria can absorb some phosphorus (as PO4) in their cell mass, using it as a nutrient catalyst in the production of enzymes and proteins. The bacteria also use phosphorus in cell reproduction, making it unavailable as a food source for algae and aquatic plants.


Two strains of Pseudomonas putida, used in various Alken Clear-Flo® 1000 line formulas, are designated as "phosphate accumulating", which means that under aerobic conditions, they will accumulate more phosphate than is needed as a nutrient for cell mass survival and growth. These same strains will release phosphate under anaerobic condtions or when they die, so "phosphate accumulating" is not a universally perfect solution to the presence of phosphate, as some competitors advise. We also have an Acinetobacter strain, used in certain wastewater treatment formulas, that is also a phosphate accumulator.

13. How does Alken Clear-Flo® or Alken Enz-Odor® control odor?
By accelerating the natural nitrogen cycle, various Alken Clear-Flo® formulas enhance the rate at which ammonia is converted into nitrite and then into nitrate, eliminating the release of ammonia gas. Besides the known strains of nitrifiers, found in Alken Clear-Flo® 1100-50x and 7110-50x, we have two strains of Paracoccus pantotrophus and one strain of Bacillus mojavensis that oxidize ammonia heterotrophically to nitrite. You can find the heterotrophic ammonia oxidizing strains in CF 1003, 1005 and Alken Enz-Odor® 6.


A number of Alken Clear-Flo® and Enz-Odor® products contain special strains selected for their ability to biodegrade hydrogen sulfide, eliminating these odors as well. Specifically, you can find them in Alken Clear-Flo 1003, Alken Clear-Flo 1005, Alken Clear-Flo 1008, Alken Clear-Flo 1400-50x, Alken Clear-Flo 7114, Alken Clear-Flo 7139, Alken Enz-Odor 2, Alken Enz-Odor 4, Alken Enz-Odor 5, Alken Enz-Odor 6, Alken Enz-Odor 8, Alken Enz-Odor 9, Alken Enz-Odor 10, Alken Enz-Odor 12. Alken Nu-Bind, Alken Nu-Bind 2, Alken Nu-Bind 3, and Alken Treat-A-Loo 2.

14. Where can Clear-Flo® be used?
Clear-Flo® products have been used for lakes and ponds, industrial wastewater, aquaculture, landfill leachate, greenhouse irrigation water, agricultural waste, groundwater pollution and restaurant waste. Since many pollutants are ubiquitous, applications are numerous and ever expanding.
