There is a lot of talk on ZEOvit.com with regards to the accuracy of the test.
Not running tests correctly or using Fresh water tests for saltwater tanks

That's too bad!

A month or two ago when I was at one of my more "at wits ends" moments with regards to why my SPS keep dying - I called up some local labs (well drinking water testing and so on), .. a "drinking water panel" which included about about a dozen parameters of interest to us as aquarist would have run about $100 (maybe a little less, don't remember exactly). But it didn't have phosphate! That would have been an additional $15. So .. um .. yeah, I haven't pursued this avenue yet. Problem is I'm reasonably certain my testing isn't too far off - so it might just be a case of $115 to confirm that my #'s are where I think they are - and that the problem is more biological in nature rather than chemical. :neutral:
