How Algae Lift Works: The Science Behind Lifting Algae with Hydrogen Peroxide 

Algae can quickly become a big problem when it comes to water health. Algae clings to rocks, jetties, logs, and any other decorative features you have. And this can make it a challenge to get rid of. You can try scrubbing, but it’s very time-consuming. You can also try chemical treatments, but this will only encourage more algae next time (because algaecides kill the “good” guys too—bacteria who compete with algae).

Another option is Algae Lift. Algae Lift works differently by using granular hydrogen peroxide to gently lift algae off surfaces. It skips harsh chemicals, loosening algae so natural bacteria can break it down. This process is highly effective and much better for the environment.

In this blog, we’re looking at Algae Lift in more detail and unpacking how it works.

What Is Algae Lift and Why Is It Different?

Despite what you might think, Algae Lift is actually not an algaecide. It’s a peroxide-based treatment that lifts algae from hard surfaces, allowing nature to handle the rest. 

Once algae are detached from the surface they’re clinging on to, they’re exposed to bacteria that naturally decompose them. Because Algae Lift breaks down into water and oxygen, it leaves behind no toxic residues and is safe for aquatic life when used as directed. 

How It Works: The Chemistry in Action

Here’s how it works: 

Oxidation of Chlorophyll-a

The hydrogen peroxide in Algae Lift oxidises the algae’s cell walls and chlorophyll-a pigment. This weakens the algae’s hold on surfaces and makes them easier to remove.

Oxygen Release Supports Breakdown

As Algae Lift dissolves, it releases oxygen into the water. This burst of oxygen not only helps detach algae but also creates a healthier environment for bacteria that then digest the lifted algae.

Pro Tip: Use Algae Lift in combination with Biostim Accelerator, so the “good” bacteria in Biostim Accelerator can rapidly break down the algae that detaches.

Granular Targeting

Because it comes in granular form, Algae Lift can be applied directly to the problem area. The granules sink, settle, and begin working exactly where the algae are attached, making it cost-effective and precise.

When Algae Lift Is the Right Choice

Algae Lift won’t suit every situation, however, it works great in many. For example, if the algae has been there a long time, there’s a good chance you need something strong to loosen it and get the ball rolling. In some cases, you may want to maintain balance in the water and protect fish and other aquatic life.

In both of these scenarios, Algae Lift is a great option.  

Use Algae Lift when:

  • Algae are attached to underwater rocks, jetties, logs, or decorative features.
  • You want quick results (used in tandem with Biostim).
  • You want a residue-free treatment that is safe for plants and aquatic life.
  • Manual scrubbing is difficult and algae keep reattaching after cleaning.

Algae Lift may not be ideal if:

  • You are trying to treat suspended algae (green water).
  • Your waterbody is nutrient-rich or has heavy organic sludge. In these cases, Algae Lift should be paired with bacterial treatments or nutrient binders.
  • Water temperatures are below 10°C, since both oxidation and bacterial follow-up slow down in cooler conditions.

Quick Checklist: Is Algae Lift Right for You?

If you’re wondering whether Algae Lift is the right choice for your specific situation, here is a table to help you decide: 

Condition 

Is Algae Lift Right Suitable? 

Algae clinging to rocks or surfaces

Yes

Green water (suspended algae)

No

You want eco-safe results

Yes

You need rapid spot treatment

Yes 

You want long-term algae control

No, use Biostim instead 

Thick organic sludge buildup

No, use Biostim instead 

 

Practical Benefits of Algae Lift

If you find yourself in a position where you need Algae Lift, the good news is, there are plenty of benefits you can enjoy. Let’s take a look at what they are: 

Benefit 

Description 

Eco-friendly breakdown

Dissolves into water and oxygen only, leaving no harmful residues

Gentle on aquatic life

Safe for fish, plants, and other organisms when dosed correctly

Fast, visible results

Algae detach quickly, float up, and can be netted or left for bacteria

Economical and spot-specific

Targets only the problem areas without treating the whole waterbody

Enhances natural cleanup

Oxygen release supports bacterial breakdown of organic material

 

Application Guidelines and Best Practices

  • Spot treatment: Spread about 100 g per square metre over algae-covered areas.
  • Volume dosing:
    • Large waterbodies: 6-36 kg per megalitre of water volume, or 9-45 kg per surface acre.
    • Small ponds or features: 20-40 g per 1,000 L.
  • pH considerations: Algae Lift may temporarily raise pH. It works best when water is in the 6.8–7.8 range.
  • Optimal conditions: Apply directly to submerged algae. If mats are very thick, disturb them gently before dosing so the product can reach more surface area.
  • Combine with Biostim Accelerator: For improved results, pair Algae Lift with microbial boosters such as Biostim Accelerator at the time of use to speed up the degradation of algae once lifted from surfaces.
  • Follow Up Treatments: We recommend treating your water with Biostim after using Algae Lift to prevent the algae returning. After all, Algae Lift tackles the symptom of the algae but not the cause. Whereas Biostim tackles the cause and can prevent the algae being problematic again in the future.
