- Helps improve water clarity naturally
- Supports a more stable biological system
- Helps reduce sludge and waste buildup
- Supports healthier conditions for fish and plants
Ideal for freshwater aquariums, ornamental ponds, koi ponds, and routine biological maintenance.
Why customers care
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.
When water biology gets overwhelmed, problems stack up fast.
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.
- Cloudy or dull-looking water
- Waste and sludge accumulation
- Instability after water changes or cleanings
- Systems that look better briefly, then slide backward
What is DPW?
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.
Feeds the right biology
DPW acts as a highly usable support source for beneficial bacteria, helping them get to work faster once introduced into the system.
Supports stronger colonization
In water systems, long-term performance depends on bacteria establishing on surfaces and media. DPW helps support that process.
Improves consistency
Instead of short-lived activity, Bio-Pure is designed to help beneficial microbes stay productive longer and recover better after disruption.
DPW helps turn added bacteria into an active cleaning workforce.
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.
- Supports faster re-establishment after water changes
- Helps bacteria process waste more effectively
- Supports clearer water and less visible buildup over time
- Helps stabilize the system instead of creating temporary improvement
Plain-English Summary
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:
- “Wake up” faster after being added to the water
- Multiply more rapidly, increasing population strength
- Establish stronger biofilms on surfaces like gravel, filter media, and walls
- Stay active longer, instead of fading out quickly
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.
Result:
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.
From stressed water to a stronger biological system
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.

Common questions
Is Bio-Pure a replacement for filtration?
No. Bio-Pure is designed to support the biological side of your system so your filtration and overall maintenance program can work more effectively.
Why does DPW matter so much?
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.
Can this help after water changes or cleanouts?
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.
Who is this best for?
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.
Dosing chart: how much to use per gallon
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 |
Bottle sizes
8 oz treats up to 7,000 gallons. 32 oz treats up to 28,000 gallons. Best used within 18 months.
Strength
450 million CFU per ounce (24 hr HPC), with DPW microbe food built in.
Koi ponds, water gardens, fountains and aquariums
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.
What it works on: fish waste, sludge and ammonia
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.
Water temperature and seasonal use
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.
Frequently asked questions
How much beneficial bacteria does my pond need?
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.
How often should I add it?
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.
Does water temperature matter?
Yes. Use it in water above 50°F. Biological activity slows in cold water, so treatments are for the warmer months.
Is it safe for fish, plants and pets?
Yes. The label states it is safe for animals, humans, plants and pipes, environmentally safe, all natural and biodegradable.
Will the water go cloudy?
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.
Can I use it in a saltwater aquarium?
Yes. The directions cover fresh or salt water aquariums, as well as ponds, fountains and aquaponics.
