Algae Control

Algae Control

With fish waste, uneaten fish food, sunlight, and the right temperature, algae can quickly get out of control in your pond. Between pea soup green water to string algae in your waterfall, we have the treatments to get your pond back on track. The majority of these treatments will kill the algae for a quick fix, but they will not prevent regrowth. Once the algae is treated, use proactive products such as beneficial bacteria to reduce future growth.

Liquid Algae Control

Effectively eliminate many types of green water algae, and string algae in self-contained ponds with liquid algaecides. Aeration must be continuous to prevent fish loss.

Dry and Tablets

Dry concentrated formulas utilize the latest in oxygen technology to remove string algae quickly and efficiently from streams and waterfalls- best used as a spot treatment. Use tablets as a preventative in ponds and fountains.

Microbe-Lift Algaway 5.4 Algaecide

Compare to AlgaeFix, same active ingredient and 20% more concentrated.

Algaecide For Ponds - Stops Algae Growth & Controls string algae!

No more green water with ALGAWAY 5.4 Algaecide!

It stops algae growth in ponds and can be applied to areas that contain fish and plants!

For use in self-contained ornamental ponds and fountains without any outflow. For small ponds with heavy algae growth, clean the excess algae off the sides and ornaments before adding ALGAWAY 5.4 . This will reduce the amount of decaying organic matter.

Fountains, Small Ponds with goldfish and koi - Treat only those fountains and ponds which will have no outflow after treatment. High water temperatures cause more rapid natural decay of dead algae which can cause fish distress. If animals are present clean out excess algae as stated above or use before temperature exceeds 75°F (24°C).

CAUTIONS: In ponds, insure that water is well aerated via waterfall, fountain or other method to prevent fish loss. Aeration must be continuous. Not safe for use with snails, shrimp and other crustaceans or mollusks.

Repeat dosage once per week.

Biosafe GreenClean Granular Algaecide For Rapid Algae Control

Through the power of oxidation, GreenClean Granular Algaecide breaks down algae cells on contact!

Its unique, organic chemistry immediately begins fighting algae blooms and releasing vital oxygen into the water as it biodegrades. This solution can be used as a curative or preventative treatment in any water feature. Formulated without the use of harsh chemicals or chlorine, you will be worry free because nothing negative can effect your aquatic ecosystem. Trust GreenClean to immediately kill algae in any water feature around your home including ponds containing fish, plants, and aquatic life. GreenClean is an EPA registered, organic algaecide, so you can feel good about what is in your water.

  • Controls string algae in ponds, waterfalls, streams, and rocks
  • Safe for use around pets, birds, fish, and aquatic plants
  • Copper alternative
  • Works on contact
How Does GreenClean Granular Work? GreenClean is a granular algaecide with an activated peroxygen chemistry that works through a powerful oxidation reaction to break down algae cells on contact. An added benefit, the process releases oxygen into the water as it works to eliminate algae.

I Have Fish In My Pond: Can I Use GreenClean? GreenClean will not harm fish or aquatic life. GreenClean once diluted in water is non-harmful to animals such as birds, bees, and pets.

Can I Use GreenClean On My Waterfall? Yes, as a contact algaecide the granules need to make contact with the algae to be effective. Our recommendation for treating waterfalls is to turn the pumps off, apply GreenClean directly to the algae, and then turn them back on after 20 minutes.

Will GreenClean Affect The pH Level? GreenClean will raise the pH up to 1 unit. Although this will comeback down on its own within about a week. Test pH prior to using and apply in the morning. 

Note: This Product is Toxic to Birds in Raw Form

Microbe-Lift OPC - Oxy Pond Cleaner

Break Down Unsightly Debris! Microbe-Lift Oxy Pond Cleaner will safely yet immediately breakdown accumulated debris from rocks, streams and on waterfalls. Microbe-Lift OPC, Oxy Pond Cleaner will safely spot-treat all areas of light-to-heavy accumulations of debris on rocks, waterfalls, streams, planters, etc. Microbe-Lift Oxy Pond Cleaner is 100% safe when used as directed.

  • Uses Oxygen Power to break down unsightly debris
  • Especially helpful on streams and waterfalls
  • Deep cleans planters and rocks
  • Helps to prevent pond odors
  • Oxidizes and Detoxifies

Directions: Microbe-Lift OPC, Oxy Pond Cleaner is not temperature sensitive but works best in warmer weather. To achieve the best results, manually clean out as much accumulated debris from the pond as possible and shut down waterfalls before cleaning. Do not dilute. To treat areas with debris build up, sprinkle over areas needing treatment. Make direct contact but avoid live plants where possible. To maintain a continued proper ecosystem in your pond, always add Microbe-Lift PL, or any bacterial/enzymatic treatment, 48 hours after using Microbe-Lift Oxy Pond Cleaner.

Before Use: Use Microbe-Lift Ammonia Test Strips to test for the presence of ammonia in your pond water. If ammonia levels are above 0.8mg/L, DO NOT apply Microbe-Lift OPC, Oxy Pond Cleaner until the ammonia level is brought down below 0.8mg/L. If ammonia levels exceed 1.0mg/L, add Microbe-Lift Ammonia Remover.

After Use: Ammonia levels should be monitored for two days following applications of ANY/ALL oxygen release compounds as they can kill beneficial bacteria in a pond/lake resulting in an ammonia or nitrite spike. Use Microbe-Lift Ammonia Test Strips to test for the presence of ammonia. If your ammonia levels exceed 1.0mg/L., add Microbe-Lift Ammonia Remover to reduce the ammonia level to 0.8mg/L or below.

Waterfall Construction Top Tips

11/20/2018 01:33:26 PM: In the wide world of waterfalls, there are many approaches to construction. However, creating the most natural looking waterfall possible is always the bottom line. Below you'll find a list of tips that should help make the design and construction go a little smoother. Hopefully, saving you time and frustration.

Understanding Diffused Aeration

11/09/2018 11:30:31 AM: Aeration is a vital component in the health of your pond, and it's important to understand and recognize the benefits. This email will highlight specific key points and how they function to improve the overall ecosystem of your pond and/or lake.

Cleaning & Maintaining Your Pump

11/02/2018 01:09:09 PM: Eventually, your submersible pump is going to drop in performance as you'll generally notice when the waterfall flow begins to lessen. For the most part, it's not a direct issue with the pump itself but rather debris blocking the intake.

Fall and Winter Pond Care

10/31/2018 09:42:32 AM: Fall is the best season for clean-ups and clean-outs. Fish are at their healthiest and can better handle any transition during this time. With cold weather quickly approaching, it's important to know how to prepare for the harsh winter.
