When to Use RUSH®?


RUSH® is the go-to solution for improving water quality in stagnant ponds, especially those with thick, matted organic buildup and algae on the surface.

It supports balanced conditions by enhancing nutrient consumption and oxygenation.

Pair with our AquaSphere®PRO or another Healthy Ponds® dispenser for maximum effectiveness during nutrient and temperature spikes.

Simply Sprinkle It On

RUSH® spreads across the pond surface, targeting visible organic matter and boosting the breakdown process using safe, eco-based oxidizers. 

Throw them directly on top of the affected areas, and wait between 24 – 48 hours to use. Best used in combination with the Aquasphere Pro.

Additional Information

Rush® improves water quality in stagnant ponds by eliminating common stagnant pond water dangers, such as heavily matted, floating organic matter on the pond’s surface. Rush® enhances nutrient-consumption activity and increases oxygenation in the water, accelerating the decomposition of floating organic matter. It is best used with the AquaSphere®PRO. This all-natural stagnant pond water treatment eliminates the dangers of stagnant pond water and treats low-oxygen environments. It spreads onto the targeted organic material and lasts 7-10 days.

Rush® – Spec Sheet

Yes. Our products are all-natural, and veterinarian approved making them safe for fish, plants, birds, animals, pets and people.

Always read the directions on the label and if you have a question please call one of our technicians.

Since our pond water treatment product is all-natural it is not possible to over-treat your pond, but it is very possible to under-treat, and the desired result will not be achieved. If you need help, please contact us and one of our technicians will be happy to assist you.

Absolutely! RUSH® works especially well when paired with Natural Blast® or AquaSphere®PRO for a complete water health solution.

Our products are about 75% effective in salt water. If you plan on treating a salt water water feature, we recommend that you double the dosage.

There is no expiration date as long as they are stored properly. They must be stored in a dry environment.

Our AquaSphere®PRO is weighted and sinks to the bottom of your pond and goes to work consuming the excess nutrients. The AquaSphere®PRO provides a patented 30-day time release of beneficial bacteria and enzymes that consume the excess nutrients in the water and remove sludge in ponds.

To achieve the best results, use the AquaSphere®PRO with our supplement Natural Blast®.

Treatment is very simple. You toss or place the correct number of products into your pond/stock tank. The pond water treatment dispensers will sink to the bottom and begin releasing the bacteria and enzymes into the water.

You’ll typically see results within 24–48 hours, depending on pond conditions and organic load.

This all depends on where you live. But we recommend treating your pond 6 months out of the year.

All of Healthy Ponds products are designed to last for 30 days. The spheres have a patented time-release feature that allows the continuous release of bacteria and enzymes over a 30-day period. Bacteria normally live for 7-10 days, so the time-release is very important. This also means that the sphere will need to be replaced because the bacteria will not be effective after 30 days. A new sphere will be needed to continue treatment.

Yes, when used as directed. If your pond contains fish, reduce the dose by half.

We recommend that you use our product Natural Blast® for 30 days.

  • Day 1 – Recommended amount of Natural Blast®
  • Day 15 – Recommended amount of Natural Blast®
  • Day 30 – Recommended amount of Natural Blast® and recommended size of AquaSphere®PRO

Continue treatment until smell dissipates and maintain with monthly AquaSphere®PRO treatment. We encourage our customers to keep extra Natural Blast® on hand in case any problems arise.

Blue/green algae (cyanobacteria) can produce toxins that are harmful to people, pets, livestock, and wildlife. If you see signs of a bloom (green scum, pea-soup water, or surface mats), treat the situation carefully:

  • Do NOT swim, fish, or draw water for animals or irrigation until the algae is gone and the water is safe again.
  • Do NOT apply algaecides directly. In New Zealand, chemical treatment of blue/green algae in ponds and waterways is highly restricted and can actually make the problem worse by releasing more toxins when the algae cells break apart.
  • Safer approaches include:
    • Physical removal of surface scums where practical (using nets or pumps, and disposing of material away from water).
    • Improving water circulation and aeration, which reduces the stagnant conditions algae thrive in.
    • Reducing nutrient inputs for example, diverting runoff, limiting fertiliser near water, or planting buffer vegetation around ponds. Less nitrogen and phosphorus = fewer blooms.

After removal and/or treatment of algae, RUSH® All Natural Algae Treatment can be applied to visible areas, where it works by targeting organic matter and accelerating natural breakdown using eco-based oxidizers rather than harsh chemicals.

After the immediate bloom has been managed, additional all-natural products help restore balance by boosting beneficial bacteria, improving oxygen levels, and reducing excess nutrients creating a healthier aquatic environment that makes it harder for blue/green algae to return.

Please Note: Our products are NOT algaecides, they do not ‘kill algae’ directly.

Algae feeds off of excess nutrients that are in the water. These nutrients can be introduced into the water in numerous ways. Some of the most common are food remaining on an animal’s mouth when it comes to drink, leaves, grass clippings and run off. With warm temperatures and stagnant water, anything organic in the water will decompose releasing nutrients that the algae feed off of. The beneficial bacteria, in Healthy Ponds® by Bioverse® spheres, will consume the excess nutrients and starve off the green organic matter.

It is recommended to begin pond water treatments once the water has reached 7° C and continue throughout the season ( for New Zealand this is from Autumn into Summer). At this temperature, the bacteria is most active. It is more cost-effective to prevent the problem than it is to address the problem after it is established.

  • Reapply every 3–7 days as needed

Note for fish ponds: Reduce dosage by 50% and treat every 2–3 days to avoid oxygen depletion.

Tip: Organic matter decomposition can temporarily lower oxygen levels — aeration is recommended.

Dosage:

  • 4.5 kg treats 946,000 L
  • 11.25 kg treats 2,365,00 L

Application:

  • Ponds: 4.5 kg per 946,000 L every 7 days
  • Ornamental Features: ¼ cup per 9,000 L (9.5 m³)

Important Notes

  • Do NOT apply other Bioverse microbial products within 24 hours of RUSH® treatment.
  • Always calculate pond size:

Safety & Oxygen Guidance

RUSH® and other microbial products require oxygen for effective bioremediation.

Risk factors: Low oxygen + high organic matter + large fish populations = possible fish death if untreated.

Recommendations:

  • Test oxygen levels before treating fish ponds.
  • Use aeration systems in fish-heavy ponds.
  • Avoid treating stagnant, shallow, or heavily stocked ponds without addressing oxygen first.

Pond Health Facts

  • Heat reduces oxygen levels in water.
  • Fish overstocking and excess debris lower oxygen.
  • Shallow ponds naturally hold less oxygen than deeper ones.
  • Make sure the water temperature is 7⁰C or above
  • Repeat every 7-10 days. as needed
  • Repeat every 2-3 days when treating floating organic matter
  • Spread directly on the surface
  • Reduce the dosage by 50% and treat every 2-3 days in ponds with high fish populations
  • Evenly distribute
  • Keep any extra RUSH in a dry place
  • Do NOT over-treat
