Biostim Pellets 10kg

Our top recommendation for large pond and dam water treatments. Biostim Pellets are an all-in-one biological water treatment that will improve your water quality and support your aquatic ecosystem.

If you’re looking for an all-natural, chemical free, (and very effective), solution for dealing with aquatic nasties? Want the added perk of easily cleaning up your dam or pond in the process?
Your search ends here!

Key Benefits:

  • Biologically digests sludge (fancy way of saying it eats the muck on the bottom of your pond)
  • Supports the ponds natural ability to fend off algae.
  • Completely fish friendly and safe for all other aquatic life in your water body.
  • Highly concentrated formula.
  • Fast acting.
  • No sludge = no nutrient rich compost to feed nasties.
  • Low dose rates – a little goes a long way.
  • Scientifically formulated in natural water – not built in some sterile test tubes that pretty much guarantee death on application.
  • Hundreds of happy customers.


Dosage Instructions:

Initial Dose Rate

10kg per surface acre of water

Maintenance Dose Rate

5kg per month per surface acre of water.

These dose rates are guidelines that may need to be increased or decreased according to your individual conditions.

It is recommended to treat, monitor results and adjust your dose based on results.

You can expect to see a reduction of the sludge layer by 2-6″ per month when recommended dosage rates are followed.

Results also depend on sludge composition, water temperature and water movement (circulated/aerated water provides best results).



Simply toss Biostim Pellets into your water body much in the same manner as you would scatter chook pellets.

Best results are achieved when dosed regularly:
Think of bacteria like kids on a sugar high – but you want to keep them bouncing so keep the sugar coming and keep dosing the bacteria!
