ALGO UNIVERSAL*
Effective algae control
• Safely effective against the most frequently
occurring algae types, string algae, slime algae
or brown algae
• Inhibits algal metabolism
• Reduces new algae formation
• Effective without controversial copper additives
AlGo Universal is the universal talent for control-
ling algae. Whether string algae, slime algae or other
species of algae, the effective ingredient is uniformly
consumed by the algae. AlGo Universal develops
its effect over the course of 2 to 3 weeks. It acts in
the entire pond and thus it is also suitable for areas
that are difficult to access. If used as intended it is
well-tolerated by plants and animals in the pond. We
recommend use in the initial stages of algae growth.
ALGO DIRECT*
Quickly effective against
string algae
• Works through direct contact
• Ideal for locally limited infestation, e.g. in
watercourses
• Active ingredient also suitable for swim ponds
• Including KH quick test for a safe application
• Effective without controversial copper additives
Because string algae loves clear, healthy pond water,
pond owners frequently see themselves confronted
with an infestation. Usually the growth is limited to
local areas that can be specifically treated with AlGo
Direct. Algae is killed off within a few hours’ time. In
this process the active ingredient decomposes into its
naturally occurring components, this also allows use
in the swim pond (comply with the safety wait time).
Safe applications requires a carbonate hardness of at
least 3°dKH. A test strip is included.
*Use biocides carefully. Always read the label and product information before use!
