Poor Randy must feel like kicking his dog (if he has one) every night when he reads about people buying bacteria in a bottle!!! Makes me giggle just thinking of him reading these posts!!! My pond doesn't have water yet but I sure am thinking about a lot of people I've never met in person (thank God)!!!
Hey Lisa don't worry about me. Feel sorry for the people spending their hard earned money on those bottles of placebo fluid, dumping jug after jug into their ponds thinking they are adding live bacteria.
Like I've said before, rather then trying to reason with people to stop wasting their money I aught to be jumping on the band wagon and selling my own bottles of bacteria. It's not hard to sell bottles of water with bacteria in them. It takes more effort to try and kill off or neutralize any bacteria in a bottle when you seal it then it does to seal bacteria in there. But the fact is, the sort of bacteria we want to culture in our ponds and bio-filters needs oxygen to survive and be active and viable, and you just can't seal that sort of bacteria in an air tight bottle, store it on a shelf, and expect it to be any more active and viable then the bacteria that can already be found in your pond water.
There certainly are things you can add to your pond to jump start the viable bacteria already existing in your pond, but adding live "bacteria" from a bottle of a shelf is just not practical. You could add ammonia, pee, dog food, fish food, molasses, a dead frog, etc... and they will all help feed the bacteria that already exist in there, but if you want to add live, active, bacteria it must come a living active source, and that could be pond water from an existing pond, top soil, media from and active bio filter would be even better, or even scrapings from rocks in a local creek or stream, because all these sources are actively exposed to a source of oxygen which is keeping the bacteria alive and active. Take any of those materials though and put them in a container devoid of oxygen and within a day or two all the "good" bacteria will be dead, eaten, or at best go dormant.
So again, there are things that you can add to your pond or bio-filters to help jump start the bacteria already in there, but I think it's sensible to know what you are adding, and why.
