Biostim—Dredging Tablets (10kg)
A 100% natural biological stimulant
Biostim is a 100% natural biological stimulant made of bacterial cultures, enzymes and nutrients. You can think of it as a probiotic that feeds the “good” microbes (aerobic bacteria) in your dam, much the same way you might eat Greek yoghurt or drink Kombucha to feed the “good” microbes in your gut. These “good” (aerobic/oxygen-loving) bacteria actively produce enzymes, speeding up the breakdown of organic waste and degrading sludge. This reduces the amount of food available for the things you don’t want to grow.
Less nutrient rich sludge = less compost fertiliser
These “good” microbes, provided by Biostim, feed on organic material (aka the food source of algae and weeds) and draw nutrients directly from your water. Reducing the overall nutrient levels in your dam, the bacteria eventually starve out pests like algae and weeds (because, if the good guys are growing strong, there’s not much food left for anything else).
Biostim can also clear water of organic material, i.e. the cloudiness in water from microorganisms and decaying organic material. This is not to be confused with muddiness from inorganic material; Biostim does not clear muddy water.

Other benefits
Target specific areas: You can use Biostim to control sludge in the entire water body, or in specific area, such as around irrigation suction pipes, under aquaculture cages, or in swimming areas.
Reduce odour: Biostim also helps reduce odour because the “good” bacteria outcompete “bad” (anaerobic/oxygen-hating) bacteria that produce nasty, smelly chemicals like methane and hydrogen sulphide.
Non-toxic, chemical-free: Biostim is a 100% natural product that contains no harsh chemicals. This means it will not harm fish, birds, pets, or people.
Application
Biostim tablets are formulated to be tossed into your dam water. The tablets slowly break down over time. Benefits are usually seen after just a couple of weeks with sludge/organic matter being the most significantly reduced over the course of summer when bacteria are most active. Problem areas can be treated heavily without having to treat the entire water body. Biostim is safe to use at higher doses.
Dose Rates
The following dose rates are guidelines that may need to be increased or decreased according to your individual conditions. Results will depend on factors such as sludge composition, water temperature, and water movement (circulated, aerated water provides best results).
It’s recommended you treat your water, monitor the results, and adjust your dose rate based on these results.
Initial Dose
10kg per surface acre / per month
This dose rate should be maintained monthly until conditions noticeably improve, then the maintenance dose can be followed.
Maintenance Dose
5kg per surface acre / per month
This can be adjusted based on individual results.
What customers say
“In our ponds that are too small for aerators, we used Biostim pellets on their own and have noticed a huge reduction in algae.”
Andy Hart, Horticultural Curator, Department of Environment, Water and Natural Resources, SA
“We had an old irrigation system blocked by weeds. Our dam was also riddled with black sludge. Scott recommended both aeration and Biostim and within six weeks the dam became so clear I could see to the bottom of it! I was chuffed we could fix the issue without the use of chemicals.”
Michael Grant, Owner Grant’s Citrus Farm, VIC
“Visiting ducks and our pet geese were continuously fouling the dam. Scott recommended a number of systems to improve the water quality. We’re very happy with our final choice, the windmill aeration system combined with the Biostim pellets and liquid. They’ve completely cleared up my dirty dam!”
Greg Lewis, Canterbury, Victoria
