Error on Elos KH test kits

[Jim Barry]

I have been using Elos KH test kits for several years and just purchased a new one. When I tested my water, I was showing a reading of 15 dkh. Needless to say, I freaked !!!

I checked the test kit at the LFS and they also had very high readings. For anyone using these alk kits, be aware the way you read these has now changed. Instead of 1 drop = 1dkh, it is now 1 drop =.5 dkh

Here is a link from reef central.

The instructions should indicate this shouldn't they? The Elos Ca and Mg test kits have also changed recently I think. Better resolution with them now.

The paper instructions read 1 drop = 1 dkh. There is a seperate card that has been inserted with pictures. On this card it reads 1 drop =0,5 dkh. It is very confusing

Thats how my Mg was. The card shows 1 drop = 100ppm then it is crossed out and hand written in 1 drop = 75ppm? Could throw a person off if they're not careful, thats for sure.

pretty sure this was dreamt up by elios marketing team trying to double up their profit margin. tiny bit of improved measuring accuracy but costing user twice the moola.

It says the exact same thing on mine. It wasn't until I found the 0.5 part that I went ohhhhh and realized I had just wasted $15 to find out my alk was the same as my salifert kit reading

The same thing happened to me except the "finding the .5 part" I have let my alk fall to 5 dkh without realizing it

I think I'll go back to my salifert kit

It was a response to the vocal minority who DEMANDED a higher resolution, D:
