Thanks Ross! Sounds like a good idea to me then. I will get with Ken next week and discuss this option (unit is inexpensive from what I can tell). We could get more accurate results in the lab, and our drivers could test water during truck delivery. I know what you mean about killing everything. I spend all day long working on ways to improve and save, yet I can't keep blasted ich out of my son's 10 gallon aquarium. I have used everything from malachite green to formaldehyde, but I just can't keep those parasitic little buggers at bay. At present time I have opted to stick with frogs and crabs. Ryan is happy with that, so maybe "mommy the biologist" will figure out the fish part later. ? Maybe a green sunfish... ?
