These are actually ideal for the serious testing person.
They allow to accurately measure(with reference standards!!) most every parameter all in one unit.

You can use the reagents from another company or use your own(if you have the resources and know how), or buy Hach's.

They run about 800-1000$ new, so 300-400$ is good.
I have a much more expensive version, but these are easier to use and ideal for most any Aquarist situation or test.

Hach 890, Healthcare, Lab Life Science, Business Industrial items on eBay.com

Not merely to monitor, rather to measure things precisely so I no longer have to for the rest of my days. I can answer specific questions about nutrients, uptake rates etc. Then I no longer need to test. Rather, I can afford to ask specific questions and have the luxury to set up a nice experiment vs having to bother with testing frequently.

I get tired of measuring the same thing for years on end just to monitor NO3.

Simply because I suggest EI, does not imply I do not test, the real issue is how you test and why.

Those are more important than simply testing because "plant guru Bubba Lou says to test". Testing is a trade off and involves learning about the test, how to make standards, chemistry, considering what it is the data means, other factors, etc.

It can answer many many questions if you test a manipulative experiment, rather than just observation and data collection alone.

However, while I do test, I'm not ignorant of practical matters and common sense.
I know folks hate to test their water parameters and 99% are not very good about it when they do test.

But for those that are, I always suggest high grade stuff for high grade results.
