Choosing a Dye color:

*Choice of dye color should be based on contrast to the background color of the water body. For instance, FWT Red Dye offers greater contrast to heavy concentrations of algae.

*Fluorescent FWT Red Dye and FLT Yellow/Green Dye because of their fluorescent nature have a greater apparent contrast than non-fluorescent blue.

*For fluorometric testing use fluorescent FWT Red 200 Dye, it is more easily detected by fluorometric equipment.

*Fluorescent FWT Red Dye and FLT Yellow/Green Dye may also be detected visually with a simple hand-held laboratory black light (UV) at significantly lower levels - in the range of 10ppb.

*Blue Dye 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 Dye disappears in sunlight more rapidly than Fluorescent FWT Red Dye and non-fluorescent Blue Dye.

*All dye colors are resistant to the absorption of suspended matter.
