Bio-Pure combines task-oriented beneficial bacteria with Deproteinized Whey (DPW) to help ponds and aquariums process waste more effectively, support biological balance, and recover faster after maintenance.
Ideal for freshwater aquariums, ornamental ponds, koi ponds, and routine biological maintenance.

Many water problems start when biology falls behind waste load. Bio-Pure is designed to help the right bacteria establish faster and stay active longer.
Pond and aquarium owners often battle the same frustrating cycle: cloudy water, visible waste, unstable readings, stressed fish, and constant cleanup. The issue is often not just debris. It is that the biological system is not keeping up.
Deproteinized Whey (DPW) is a refined microbial support ingredient used in Bio-Pure to help beneficial bacteria establish, multiply, and remain active. It is one of the key reasons Bio-Pure performs differently than ordinary bacteria-only formulas.
DPW acts as a highly usable support source for beneficial bacteria, helping them get to work faster once introduced into the system.
In water systems, long-term performance depends on bacteria establishing on surfaces and media. DPW helps support that process.
Instead of short-lived activity, Bio-Pure is designed to help beneficial microbes stay productive longer and recover better after disruption.
Many products add bacteria. Bio-Pure is built to help those bacteria perform. That difference matters in real-life ponds and aquariums where feeding, fish load, waste, maintenance, and seasonal changes constantly challenge system balance.
Think of DPW (Deproteinized Whey) as a built-in support and fueling system for your beneficial bacteria.
Most bacteria products simply add microbes and hope they survive. But in real ponds and aquariums, bacteria need immediate energy, nutrients, and the right environment to activate, multiply, and stay effective. That’s where DPW makes the difference.
DPW provides a readily available, highly efficient nutrient source that helps beneficial bacteria:
This is critical because the real work of cleaning water happens when bacteria are attached to surfaces and actively processing waste 24/7—not just floating in the water column.
A more resilient, self-supporting pond or aquarium that can keep up with everyday waste load, recover faster from disruptions, and maintain clearer, more stable water over time.
Bio-Pure works by combining task-oriented beneficial bacteria with DPW support, helping your system process waste biologically instead of relying on harsh correction cycles.
Introduce Bio-Pure into the pond or aquarium as directed.
The formula helps beneficial bacteria establish and begin multiplying in the system.
This is where ongoing biological processing becomes more effective.
Over time, the system becomes clearer, steadier, and easier to maintain.
Supports improved clarity by helping beneficial bacteria keep up with everyday waste.
Helps manage sludge, detritus, and accumulated organics over time.
Supports a stronger biological system that can better handle normal disruptions.
Helps reduce the constant cycle of over-cleaning and short-term fixes.
Bio-Pure is designed around proprietary, task-oriented bacteria selected to support biological balance in water systems. The addition of DPW is part of what makes the formula stand out, helping beneficial microbes perform more effectively in real-world use.
This is not a generic bacteria product. It is a performance-driven biological system.
Try Bio-Pure Pond & Aquarium and experience the difference that beneficial bacteria plus DPW can make in water clarity, stability, and ongoing maintenance.
No. Bio-Pure is designed to support the biological side of your system so your filtration and overall maintenance program can work more effectively.
DPW helps support beneficial bacteria so they can establish and remain active more effectively. That can make the difference between temporary improvement and real biological performance.
Yes. One of the key values of DPW is helping beneficial bacteria re-establish after system disruption, which is when many ponds and aquariums struggle most.
It is a strong fit for aquarium owners and pond owners who want a biologically driven maintenance solution that supports clearer water, system stability, and lower maintenance frustration.
Bio-Pure with DPW helps your pond or aquarium work the way it should: cleaner, steadier, and easier to maintain.
From the directions card (020-2198). One cap is 6 ml; half a cap is 3 ml. Shake well and mix the dose into water before it goes in.
| Where | Initial treatment | Maintenance |
|---|---|---|
| Aquarium | 1 cap (6 ml) per 10 gal, every 10 days for 30 days | ½ cap (3 ml) per 10 gal every 1–2 weeks |
| Pond | 1 cap (6 ml) per 100 gal, poured around the edges | ½ cap (3 ml) per 100 gal every 1–2 weeks |
8 oz treats up to 7,000 gallons. 32 oz treats up to 28,000 gallons. Best used within 18 months.
450 million CFU per ounce (24 hr HPC), with DPW microbe food built in.
The same bottle works in koi ponds, water gardens, decorative fountains and aquaponics systems, and in freshwater and saltwater aquariums. It is safe for animals, humans, plants and pipes, all natural and biodegradable.
Fish waste, uneaten food and decaying plant matter are the raw material for everything that goes wrong in a closed system: they break down into ammonia, which nitrifying bacteria convert to nitrite and then nitrate, while the leftovers settle as sludge and bottom solids.
Bio-Pure works on the source. Its task-oriented microbes digest that organic waste and bottom solids, and the label credits the formula with reducing ammonia-, nitrate- and hydrogen-sulfide-forming bacteria and the odors they cause. Because DPW feeds the microbes from the moment they go in, they get to work sooner than bacteria left to wake up on their own.
A mild bio-bloom in the first 1–3 days is normal while the microbes gather and digest the waste; the water clears as they work.
Bio-Pure's microbes are meant for water above 50°F. Below that, biological activity slows in any pond or aquarium, so treat through the warmer months and pick the schedule back up in spring.
Dose by water volume, not by pond size in feet. The liquid treats 100 gallons per half-cap for maintenance; the powder treats 1,000 gallons per scoop. Use the dosing table above and round up rather than down.
Every 1–2 weeks for maintenance. Aquariums get a heavier initial course: a full cap per 10 gallons every 10 days for the first 30 days.
Yes. Use it in water above 50°F. Biological activity slows in cold water, so treatments are for the warmer months.
Yes. The label states it is safe for animals, humans, plants and pipes, environmentally safe, all natural and biodegradable.
A mild to strong bio-bloom in the first 1–3 days is normal, especially in a system with a lot of waste in it. It clears as the microbes digest the waste.
Yes. The directions cover fresh or salt water aquariums, as well as ponds, fountains and aquaponics.
