Test kits for the colorblind peeps

[synack]

A few weeks ago I tossed all my test kits since they were a few years old and now I need to get a new set.

I'm looking at getting:

Ca
Mg
NO3 (Nitrate)
PO4 (Phosphate)
NH4 (ammonia)
NO2 (Nitrite)
ALK (Have Salifert... fairly easy to read)

Most likely I will go with a Salifert/Elos mix.

Now, are any of these kits bad news for the color challenged people? Particularly Red/Green

I remember years ago I bought a set of seachem and redsea kits and they were awful awful awful awful awful awful hard to read. One more time... awful! Those compare the liquid to the card color chard are bad news.

Any recommendations?

Calcium and nitrate can be done with meters, although the equipment is expensive and time-consuming to use. Alkalinity can be done with a good-quality pH meter, although you seem okay with that test already. Phosphate can be done with a meter, but the meters we can get at reasonable prices aren't all that accurate, although some people think otherwise.

I have a red/green color deficiency. I have used Salifert test kits in the past and I have always had a problem seeing the color change with the Ca, Alk, Mg test kits. I have had to rely on my wife to do the test for me.

I recently tried the API Ca and Alk test kits and the color change is much more obvious. I have no problem seeing the colors. This is good because they cost less and I think they are accurate enough compared to my Salifert kits. The resolution of the API test kits are not as fine as the Salifert but good enough for me to keep my parameters within range.

For Mg testing I tried the Elos test kit. It is still a bit hard for me to see the color change, but easier for me than the Salifert. The test is a bit more of a pain since you have to do two tests to get the final value.

One thing I was going to try, but I have not yet, is to try putting on some tinted lenses when performing the tests. I am wondering if the tint in the lense might change the colors in a way for me to see the color change better. I have a couple of ski goggles with different color tints I was going to try. It is kinda a funny thought, I would look like a mad scientist when doing my water testing.

You could take a picture and adjust the balances ?
That might work.
