Our bacteria tests are package products called Enterolert and Colilert. Reagent is added to a 100ml sample, poured into a tray with multiple cells and heat sealed. After 24 hr. incubation, UV light indicates presence, number of cells glowing gives equivalent to plate count. Trained monkey could...

Okay, I'll explain what I can. First, pix of some of our smaller pools can be seen at ojospa.com (I'm not trying to advertise here) and I'll get some of the big pool, too. The pools are all hot-spring fed, several springs ranging from 109 to 131 degrees, constant temp and flow year-round. We're...
