Look foward to your results, What type or where did you get your UV Dye.

BigBen:

I have tried Auto uv Dye from Checker. Its the type for Rads in Auto's. Dye-Lite. Glows OK w/ one or two drops, anymore drops and you system will grow Algae. Same thing happened w/ that dye also.
My homemade stuff glows the strongest with little light and actually cleans the copper little by little but doesnt harm pump as far as I can see. Im using it now.

Dtek UV fades over 30 days, tested it in sealed gatorade bottle.

So I have tested these dyes:
Homemade stuff
Dtek
Dye-Lite
Directron UV dye which I believe is Dye-Lite also.

All these dye's showed same thing with my system, the water would just turn clear after 3-7 days. Usually within 3 days.

I feel no oil in dye.
