[Pond Algae Control] Sustained Algae Prevention with a Single Application. A Sustained-Release Algaecide Safe for Ponds with Fish is Now Available.

Shin-Nippon Kasei Co., Ltd. (Ichihara City, Chiba Prefecture, Representative Director: Tomohiro Iwatsuki) introduces "Aqua Guard Gel Type," a sustained-release, long-lasting algaecide and algae preventative for ponds and water features. Gel capsules made from natural ingredients derived from seaweed (alginic acid) slowly release active ingredients in water, suppressing algae growth for several months with a single application. As it contains no chlorine-based chemicals, it can be safely used in ponds inhabited by fish such as koi.

Product Details

"Algae grew again... but honestly, regular spraying is a hassle" - A product born from the real voices of the field

Many sites regularly spray liquid or powder type algaecides for pond and water feature algae control. However, concerns such as "the effect wears off quickly," "each application is troublesome," and "strong chemicals cannot be used due to concerns about affecting fish" have been raised for many years by golf course and park managers.

Aqua Guard Gel Type was developed in response to these voices from the field. Thanks to its "sustained-release" mechanism, where gel capsules containing active ingredients gradually dissolve in water, the algae prevention effect lasts for approximately 3 months in summer and up to 6 months under certain conditions (according to our company's research), with an onset of effect within 2 weeks to 1 month after installation. Simply fix the gel in a net bag to the perimeter of the pond with the included rope; frequent spraying is unnecessary.

Product Features

1. Effect lasts 3-6 months - No need for frequent spraying (*)

Since the gel capsules slowly and continuously release active ingredients, the effect lasts for approximately 3 months in summer and up to 6 months under certain conditions (according to our company's research) after installation. This eliminates the hassle of regular spraying required for liquid or powder types. It has the characteristic that the release amount naturally changes with water temperature, allowing for year-round use.

* The period until the effect appears and the duration of the effect may vary depending on the environment.

2. Safe to use even in ponds with fish

It uses alginic acid, a natural ingredient derived from seaweed, to gel the active ingredients. Since it contains no chlorine-based chemicals, it has a low environmental impact and can be safely used in ponds inhabited by fish such such as koi, provided the appropriate amount is used. It also causes less damage to painted surfaces, making it suitable for artificial ponds and water features.

3. Simple installation and removal - Just fix with the included rope

Simply place the gel capsules in a net bag and fix them to the perimeter of the pond with the included fixing rope. If multiple units are used, distributing them as evenly as possible will spread the effect throughout the entire pond. When replacing, the net bag can be collected as a whole, making cleanup easy. No special equipment or expertise is required.

4. Effect returns after rain - Stable management possible due to sustained release

Even if the agent is temporarily diluted by rain, the sustained-release gel continues to release active ingredients, restoring its effect. Stable management is possible even in outdoor aquatic environments.

Gel Type vs. Liquid Type (FSX-1) - What's the difference?

Aqua Guard series offers multiple types to suit different uses. If you want to remove algae quickly, FSX-1 (liquid) is ideal; if you want long-term, hassle-free management, the Gel Type is best.

"Among the many voices we've heard over the years from sites struggling with pond algae control, the most common complaints were 'the effect doesn't last' and 'management is a hassle.' While liquid algaecides have an immediate effect, their duration is short, posing the challenge of frequent applications. Aqua Guard Gel Type, once installed, maintains its effect for several months. The fact that it can be used in ponds with fish because it doesn't use chlorine has also been highly praised by many customers. We highly recommend this product to those managing large water features such as golf courses and parks."
