Randy---Potassium test kit

beaslbob · Aug 5, 2015

Randy.

Saw a red Sea test kit which had a potassium titration test kit. Also an iron kit. Forgot what the third kit was for. maybe iodine.

here: http://www.redseafish.com/coral-coloration-program/coral-colors-pro-test-kit/

Looked it up and it is the coral colors test kit for iron, potassiun, and Iodine.

I think they are titration and the potassium claims to be sensitive to 3ppm.

I know these things don't have to be watched all that closely but I was wondering if you thought the kits would be accurate.

I've not used a titration kit for potassium, so I'm not sure how well it works or how accurate it might be. The kit I used a few years back from Fauna Marin for potassium certainly wasn't that accurate or precise.

FWIW, the iron kit isn't very useful as iron need never be high enough to detect with a kit.

It works, but the color change is subtle in the titration. It takes a few uses on it before you get somewhat accustomed. And once I got comfortable with the kit, I liked it better than the Salifert K test kit.

thanks.

I had they fauna and it seemed to be not too precise or accurate. At least from color scale anyway.

Just adding my experience for anyone looking for info on the Redsea K test kit. Its terrible! It takes over 20 minutes to complete a test and the color change is so subtle that its very easy to miss and will almost certainly require 2-3 tries to figure out. And considering there's only 40 tests in a kit, that's not very good. I've used lots of test kits from different brands and this is by far the most user unfriendly test I've seen. I understand its probably difficult to develop and sell a K test kit for aquarists to use, but this one is terrible. Save your money and just send in a triton test if you want to know your K level

And what is happening with Salifert K test? @Habib(Salifert) ?

I hope I don't break the forum rules...

We will ship out again middle of November.

We were not satisfied with a new batch of a commodity but that has been solved now. So will start producing again.

dern

even got a reply from Habib.

FWIW just found this video

I am so happy to see this. I just hope we get it as soon in Europe too.

Anyone else using the Red Sea Pro kit? I've found all of Red Sea Pro kits to be fairly user-UNfriendly as far as time and number of steps, but it makes me feel like I'm getting a more accurate result.

I've used the Zeovit and Elos potassium kits, both of which seem to essentially be the same test kit. I think it's only as accurate as your eye, and you can certainly get different answers under different light sources, so I like the idea of a potassium titration.

RS Potassium test kit is useless. It is expensive, it takes half an hour to make the test and finally it was impossible at least for me, to see the color change from purple blue to blue. salifert potassium is far better.

Wish I had read this before I got the red sea kit. Tried it today and also could not tell the color change. After watching the video I'm going to try again tomorrow. It is time consuming. That red sea guy makes it look so simple though.

Yes it is. Or at least I assume it is because we can get it in Canada now, and you guys in the US always get things first.

Good to know, thanks! I'll get the Salifert one then.

The Red Sea Potassium require warmwhite light to see the color change. In aquarium light it is invisible.
But Salifert is so much easier to use, cheaper and I beleive in stock everywere now.
