Friendly Posted August 7, 2017 Share Posted August 7, 2017 I'm color blind, so these color tests have always been a frustration for me. however, tests need to be done, so I'd like to know what kits you prefer. if anyone else is also badly color blind, how do you cope? the Hanna option is very attractive, however it would be quite expensive...likely $1000 more more to get all the testers needed, being there's a high range and low range for each parameter. can anyone recommend which Hanna tester(s) would be most beneficial to get up front?

Pjanssen Posted August 7, 2017 Share Posted August 7, 2017 I just have the alkalinity hanna checker and love it. Plan to get the calcium one when I'm out of my salifert. I like salifert because your not looking for a color comparison, but rather a color change, so if you can see a difference than that might be an option for you. I believe Red Sea is the same. 1 Quote Link to comment

Thrassian Atoll Posted August 8, 2017 Share Posted August 8, 2017 I just purchased a ton of testing kits. Hanna alk DKH checker and I like it. Super easy to use, great reviews. Hanna ultra low phosphorus checker. Great reviews, but I need to figure out a better way to use it with the powder and running out of time to do the test. Hanna Ph probe to test it against my Apex probe. Pretty spot on for both. Red Sea Calcium test kit. I like it. Good reviews. The range between 400-500 is so tiny though, kind of hard to see imo. red sea nitrate - I like this. Easy to use. If you are color blind though, not a good option. I bought a Red Sea magnesium test kit but haven't received it yet. Stay away from the Hanna Calcium checker. Nothing but awful reviews for it. 1 Quote Link to comment

Sure. with the Salifert kits , For calcium the color goes from pink/red to blue. A drastically different color. It will change first to a purple, and then a blue. I haven't used the alkalinity in awhile, but if I remember correctly the color goes from blue to pink. With the magnesium it goes from pink to gray or blue. Phosphates, nitrates are a color comparison though, sorry. Hope this helps 1 Quote Link to comment
Clown79 Posted August 8, 2017 Share Posted August 8, 2017 Hanna checker for alk and phos. Digital would be easiest. Ca and mag- red sea. The colour goes from red to blue. It's very distinctive. Or Hanna checker The Api's are too difficult to tell the difference in colour. They are a pain. 2 Quote Link to comment

I read multiple reviews about the Hanna calcium checker always reading super high. I am staying away from that one. That's to bad too, I really like the Hanna checkers. 1 Quote Link to comment
4x5 Posted August 8, 2017 Share Posted August 8, 2017 Salifert are great IMO. It's pretty obvious when the colour has changed. 1 Quote Link to comment

Hope this helps hmmm...interesting! how do you range the color changes to how many ppm you're testing for? ie, you said when testing Ca, it goes from pink/red to blue...but turns purple first. I would probably have trouble distinguishing purple from blue. does purple mean (random numbers generated) 1 while blue means 2 or is the purple insignificant as it's just one stage of the reaction before you have your real answer?

I have to agree on the salifert, the color changes are prety dramatic and then you just read thenumbe on they syringe. That said, there are many variations of color blindness and what colors one person can distinguish may be drasticly differant from what another person can. OP, you are going to do some trial and error. Are there any aquarium societies or clubs in your area? Perhaps you could join one and ask the membership for help figuring which work best for you.

yungKitten Posted August 9, 2017 Share Posted August 9, 2017 @Friendly What type of colorblindness do you have? (I.E. Red-green, Blue-yellow or total? Possibly other.) This could help people suggest stuff more accurately. What I will say is avoid API. Quote Link to comment
Friendly Posted August 9, 2017 Author Share Posted August 9, 2017 I'm primarily red/green...but it goes into everything. I did the color blindness test the other day...18 color's to line up. I got only the first two right. an example...the other day my wife asked me about a color. I said gray. it was some light blue/purple. 1 Quote Link to comment
