Choosing a product
color:
Choice
of color should be based on contrast to the background color
of the water body. For instance, FWT Red offers greater
contrast to heavy concentrations of algae.
Fluorescent
FWT Red and FLT Yellow/Green because of their fluorescent
nature have a greater apparent contrast than non-fluorescent
blue.
For
fluorometric testing use fluorescent FWT Red 200, it is more
easily detected by fluorometric equipment.
Fluorescent
FWT Red and FLT Yellow/Green may also be detected visually
with a simple hand-held laboratory black light (UV) at
significantly lower levels - in the range of
10ppb.
Blue
is frequently used for decorative effects, evaluation of
household systems, and generally where the blue may be more
acceptable to public view.
FLT
Yellow/Green disappears in sunlight more rapidly than
Fluorescent FWT Red and non-fluorescent Blue.
All
colors are resistant to the absorption of suspended
matter.
