Water samples were taken at the beginning of the trial, prior to Biostim being used. We then treated the lake with a standard dose of Biostim—applying Biostim fortnightly for the first 6 weeks, then once a month. No other method of treatment was used, e.g. no aerators, chemicals or manual removal took place.
You can view the results below but essentially what happened is the populations of "good" microbes immediately began to grow when Biostim was introduced.
These "good" microbes consume nutrients in the water as part of their metabolic processes. So more "good" bacteria means more organisms consuming nutrients (the same nutrients algae and blue-green algae depend on to survive).
In just weeks, the populations of "good" bacteria got so high nutrient levels dropped to a range where the algae and blue-green algae could no longer properly feed and grow. And so the pests starved to death.
The clarity of water also improved because the increased populations of "good" bacteria consumed more decaying organic debris (leaves, poo, dead insects etc) floating in the water.
Biostim Pellets and Tablets are primarily used for reducing sludge. The products are essentially the same thing, the tablets are just slightly more potent. The pellets/tablets sink to the dam floor and settle in the sludge, dissolving over weeks. This provides life-sustaining resources to populations of “good” microbes so they can eat away at the sludge.
Biostim Powder treats both the water column and floor, making it ideal for clearing organic murkiness from your water and treating small amounts of sludge. Dropped into your dam in water-soluble bags, the powder saturates the water column before the last of it settles on the dam floor.
Biostim Liquid is ideal for new dams to spike the water and for dams with high amounts of suspended debris, i.e. murky-looking water, but little to no sludge. It is the fastest acting probiotic in the Biostim range. The solution spreads quickly through your entire water column and wakes the microbes up.
Biostim Accelerator is a biocatalyst that speeds up the degradation of dead and rotting weed and algae, making it an ideal companion for use with algaecides or herbicides. Without it, dead rotting material can remain floating in your water for weeks and will often end up on the floor of your dam becoming fertiliser for next season's algae/weed.
Biostim Booster Blocks are highly concentrated probiotic blocks that can be used in wastewater and areas of super-concentrated nutrient levels. The block is tied to an object where the water is moving fast, e.g. an aerator or at the base of a waterfall. The blocks can last up to 60 days depending on flow rate.
