EcoBlast is one of the most effective tools available for quickly treating string algae on hard surfaces, but it is not always the only—or best—solution depending on the type of fountain or Pondless Waterfall you have. Understanding when to use EcoBlast versus other treatment options will help protect your feature while achieving the best results.
Using EcoBlast for fountains and Pondless Waterfalls
EcoBlast is a fast-acting, contact algaecide designed specifically to eliminate string algae growing on rocks, gravel, and other natural surfaces. It works by directly attacking the algae on contact, making it ideal for:
- Natural stone fountains
- Pondless Waterfalls with rock and gravel surfaces
- Areas with visible string algae buildup
When applied properly:
- Results are typically visible quickly as algae begins to break down
- It is best used as a spot treatment rather than a full-system solution
- Manual removal of excess algae after treatment improves long-term results
This makes EcoBlast one of the most effective options for restoring the appearance of natural water features.
When NOT to use EcoBlast
EcoBlast is not recommended for all fountain types.
Avoid using it on:
- Painted or sealed surfaces
- Decorative spitters or coated fountain finishes
- Artificial materials where surface damage may occur
For these applications, gentler alternatives should be used to prevent discoloration, peeling, or surface damage.
Better options for decorative or painted fountains
For fountains with finishes or delicate materials, use:
-
Rock and Fountain Cleaner Spray
- Ideal for light algae, debris, and mineral buildup
- Safe for decorative finishes when used as directed
-
Aquascape Algaecide
- A milder, water-treatment-based solution
- Helps control algae without the aggressive contact action of EcoBlast
These products allow you to maintain appearance without risking damage to the feature.
Using a Dosing System for ongoing maintenance
While EcoBlast is excellent for immediate results, it does not provide long-term prevention on its own. This is where an automatic dosing system becomes valuable.
An Aquascape Automatic Dosing System (XT or SL) can:
- Continuously add treatments in controlled amounts
- Help prevent algae from returning after initial treatment
- Reduce maintenance by maintaining consistent water quality
Typical approach:
- Use EcoBlast to eliminate existing algae
- Maintain balanced water conditions to limit future growth
This combination creates both a corrective and preventative solution
Fountain-specific treatments for maintenance
For smaller decorative fountains or features without biological filtration, using products specifically designed for fountains is the best long-term solution for maintaining clean, clear water and protecting finishes.
Aquascape offers several fountain-safe treatments that are formulated for recirculating decorative features:
-
Aquascape Fountain Maintenance
- All-in-one solution for routine care
- Helps prevent debris buildup, stains, and odors
- Ideal for weekly maintenance
-
Aquascape Algaecide
- Controls and prevents algae growth, including string algae and green water
- A safer alternative to harsher treatments when used as directed
-
Aquascape Fountain Scale Free
- Reduces calcium, lime, and mineral deposits
- Especially useful in areas with hard water
These fountain treatments:
- Are designed specifically for recirculating decorative water features
- Help control:
- String algae
- Green water
- Mineral deposits and scale buildup
- Are safe for a wider range of materials, including painted and finished surfaces, when used as directed
They can be used in several ways:
- As a standalone maintenance routine (weekly or as needed)
- Alongside periodic cleaning with Rock and Fountain Cleaner
- In conjunction with an Automatic Dosing System (XT or SL) to maintain consistent water quality with minimal effort
Additional considerations for algae control
No matter which product you use, algae control is influenced by several key factors:
- Sunlight exposure
- Water flow and circulation
- Organic debris buildup
- Water chemistry and nutrient levels
For example, systems like the IonGen™ System G2 reduce algae by releasing copper ions into the water, helping control string algae over time without traditional chemicals . This type of solution can be used alongside physical treatments for a more complete approach.
