Test Kit Color Test!

Matt Rogers · 06-13-2003, 05:37 AM

Playing around with a test kit again recently made me realize how subjective and prone to error people's results can be!

A lot depends on your EYES.

I am not good with colors so I have Laine back up my findings first. But still... does it bother you a bit too?

Check out this pic I took of my nitrites with a Sea Chem test shortly after I set up my hex.

What would you say it is? [smiley=stars.gif]

I would say it was a little over 1. But, you are absolutely right about tests, they are very subjective.

Any tests that you take regularly are probably going to be your more accurate ones, simply because you are used to looking for a certain color. But, as your test shows, Matt, a LOT is open to interpretation.

I wish they could give us digital tests. But, that would cost a fortune!!! [smiley=greedy.gif] [smiley=devilish.gif]

I agree it looks like its between 1 and 1.5. Very frustrating due to the subjectivity. If you think about the cost of good lab equipment, maybe what we get for less than $25 isn't so bad after all, eh?

A little over 1?
Wow. If you were to tell me it was off the scale I would believe you, that's how bad I am with this.

As for digital, I am with you buddy I want one just for this reason! [smiley=thumbs_up1.gif]

In fact, that is why I posted this digital one a while ago:

$270 for the Medusa is the cost of 3 years replacement MH bulbs!

True Craig, but it would be COOL wouldn't it?

Matt I think your Pregnant

I find with all test kits the colour is very subjective as well as for the salifert Kits drip type tests when is the colour change complete and the readings final.
I guess the bottom line is most kits have drastic colour changes between a good reading and a bad. I have discovered that I'm all over the place with test kits from 4 different makers to fine the one I like to work with best.

its hard for me to tell sometimes what the color is

i looked at it and said 1.5 (around) but when i go back and look at it the bar looks more pink light to dark where the test looks purple. but maby i was trying to hard on that one
