I need a new Alk/KH Test kit and want to possibly get 2. Right now I am using a seachem test kit right now and like it but i also want to get another one for reference. Which is better, or what is your preference Elos or Salifert?

Both kits are based on similar principle.
One big advantage to elos is I have never not seen them in stock... Salifert has a limited run with no plans of upgrading their production capabilities despite increased demand.... or so the grapevine tells me.

The seachem is as good as any. Salifert have had quality issues in the past. References aren't worth a whole lot, they are bicarbonate based which means the co2 levels in the air will affect the references.

Elos measures in .5 dkh increments. Salifert a little higher resolution. But really doesn't matter too much for our purposes. .5 is perfectly fine. Elos is easier to use but doesn't last as long. But then again, you should be replacing at least once a year so for most your not going to use it all by then anyways once your CA/ALK routine is set and pretty predictable.

Accuracy I don't consider one any better than the other. When I did a side by side test the only difference between the two where the resolution Salifert read 8.6, Elos 8.5.

I have been using Seachem kits for over 12 years.Never have had a problem,and the customer service is top knotch.If you ever have a problem with any part of any kit they will send free of charge.

LaMotte is better than all three and isn't much more $$$$. Fritz is correct in that all alkalinity test kits operate on the same principal. They measure the end point at which all the bicarbonate is converted to carbonic acid, which I believe is a pH of 4.5. ( note: this does not apply to the Seachem borate alkalinity test kit as it's completely different).

What I wish were the case is that test kit makers include an NIST reference with them. That is the only way to determine accuracy.
