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.
