Unfortunately I only have Salifert, so I am not sure how the Red Sea one works. If you can get a hold of the Salifert version and use it to test, we should have a shot at figuring out what the normalization of the KH Keeper reagent is.I tried the rs test kit and it didn’t work even diluted with 9 parts ro.
Hmm, interesting. That is the exact (diluted) normalization as the Alkatronic. They start with 0.1N and dilute it 4:1 to end up with 0.02N as well.Iirc, the kh keeper reagent is 0.2N concentrate that is then diluted to 0.02N. Only looked at it by the numbers though when reverse engineering how the thing works, didn't actually try generic acid it out on an actual unit
That sounds like a decent idea.i Have some 0.1n Hcl so I may dilute 4 parts ro to 1 part Hcl and give it a go
7.15 to be exact, and that is in 50ml, should be 0.02N yesHmm, well they show the device using 7ml of reagent for 8.0 dKH in their advertising, but I am not sure what the volume of water they are testing is.
Perhaps the test with 0.1N HCL diluted down to 0.02N will bear fruit.

To run a titration test (any device) using 0.1N hydrochloric acid in a 100ml volume of test water you need approximately 3ml of reagent (at DKH 8.4)..
If you can track the amount of water and the amount of acid being added (is that info not provided on the app??) - you can calculate the rough concentration of acid.
7.15 to be exact, and that is in 50ml, should be 0.02N yes
Yes, that would give you 4:1.so just to comfirm i should mix 200ml HCL with 800ml of RO? thanks again
