I'm running 1x 175w SE XM 15K MH on an icecap ballast inside a luminarc reflector, and 2x 28w actinic PCs on a PFO ballast. I've got my other reflector, a batwing handy so I'll leave my MHs off today, and this afternoon I'll switch out the reflector and try it for a couple of weeks.

How would I go about testing for other contaminants? I contacted AWT in the states and finally got a response, they can't test Canadian water as they can't ship it back to us, and we may have problems getting it to them.

Does anyone know of similar businesses in Canada?
