Eric - Lots of bacteria products out there for ponds, many of them are from the sewage/septic industry and designed primarily for bottom sludge reduction. Often they are sold with false promises of working miracles in your pond. Buyer beware. Many have only a few different types of species in the blend. The GOOD ones have many more species which do numerous different jobs.

Bacteria are very specific and do only one very simple job per specie; no multi tasking here! Bacteria for ponds have gotton a bad name/rap due to a lot of the "snake oil" types which are still out there with "wild promises" to clear up every pond.
