Biostim—Probiotics for Water

Biostim is a 100% natural biological stimulant made of bacterial cultures, enzymes and nutrients.

  • Starves out algae and weeds
  • Reduces sludge
  • Cleans up organic waste

Biostim is a probiotic that feeds the “good” (aerobic/oxygen-loving) microbes in your waterbody, much the same way you might eat Greek yoghurt or drink Kombucha to feed the “good” microbes in your gut. These “good” bacteria actively produce enzymes, speeding up the breakdown of organic waste in your water and degrading sludge that forms on the floor. Cleaning up this organic waste, reduces the amount of nutrients/food available for pests like algae and weeds. With enough nutrient reduction, pests are starved out for good.

Customer Story

Using Biostim, 98% of Algae and 99% of Blue-Green Algae Eradicated in 11 Weeks

In February 2022 we ran a 3-month trial in a City of Manningham council lake to measure the impact of Biostim on algae and blue-green algae. We took water samples 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. During the trial, no other method of treatment was used, e.g. no aerators, chemicals or manual removal took place.

Results in 11 weeks…
  • Algae population dropped 98%
  • Blue-green algae population dropped 99%
  • Nitrogen dropped 25%
  • Phosphorus dropped 57%
  • Level of suspended solids dropped 83%
  • Water turbidity (muddiness) dropped 62%

Products available

Biostim Pellets

Ideal for dams with a lot of sludge and dams with water moving through them (e.g. irrigation).

Biostim Tablets

Similar to pellets but a higher concentration, ideal for sludge and moving waterbodies.

Biostim Powder

Ideal for water requiring a high amount of treatment (e.g. wastewater) and large waterbodies (>3 acres).

Biostim Liquid

Ideal for new dams (to spike the water with microbes) and dams with high amounts of suspended debris (i.e. muddy-looking water).

Biostim Accelerator

Using herbicide or algaecide? Biostim Accelerator is a biocatalyst that improves the effectiveness of algaecides and herbicides, meaning you can use less chemical.

Customer testimonials

“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. WQS recommended a number of systems to improve the water quality. We are very happy with our final choice, the windmill aeration system. This combined with the Biostim pellets and liquid are cleaning up the dirty dam. Everything WQS said would happen has happened!”
