enChroma glasses cure colorblindness (supposedly) You can do a indepth test on their site and see how well their glasses will help you.

sadly they say they wont work well for my colorblindness, so I just use the hanna checkers and go with it.

That is very cool. I haven't done a test since I was in kindergarten. And it did a excellent job of perfectly describing how I see colors. Sadly mine is a strong protan and they won't really help me either.

Well I had a API dKH test on hand and figured I'd test it against my Red Sea to see how far off it was since it has a drastic change when you hit the proper dKH.
API - 10 dKH
Red Sea - 10.1 dKH
The API doesn't use decimal points though which would make it less accurate.

I can normally do pretty good with the Red Sea Mg test I've been testing a lot the past few days trying to figure out exactly what to look for on them. Getting pretty close to the same numbers I get as when the wife helps me.

Well I was kinda close on the Alk test. Thought I stopped at the perfect spot but I didn't stop soon enough.
I ran Randy's DIY alk test with .1N HCL and at 4.5 PH the Alk was 9.5dKH. That test is so simple. Much easier than looking for a color change IMO. A big thanks to Randy for posting that article.

I was just going by what Randy suggested in the DIY Alk test article. I assume that since you are taking the ph down to 4.5 with the acid is why it is recommended to calibrate with 4 and 7 instead of 7 and 10.
I can calibrate them free at work in the lab. And I don't have to pay shipping.

Yes, pH 7 and 10 are better for calibration prior to tank measurements, but pH 4 and 7 are better for alk titrations or monitoring a CaCO3/CO2 reactors (although any combination of calibration fluids should be OK since we rarely have need for high accuracy in pH).

Hi to Hig789. You could get your wife to buy you a pair of EnChroma spectacles. If you google "Enchroma" that will give the manufacturers site and googling "Colorblind Man Sees Purple for the First Time" should point to a well known video site with this and other film; not sure I should post the urls. I haven't looked into the cost of these though.
Best Wishes,
Mark.

My alk Red Sea test kit does the same thing. Goes to a beer color instead of the dark clayish red. I have checked it against other test kits and when the color changes from blue to a beer color it is done.
