Has anyone compared the calcium/magnesium from JBL with more renowned brands (like Salifert, for example)? I'm curious about how significant the error/deviation is. I tested it myself and it showed a picture that I roughly expected based on external signs... But I'm still interested.

I have both Salifert and another brand, there is no difference. It's just that Salifert lasts longer.

On the other hand, it is absolutely NOT analogous to the salifert, which lowers significantly. JBL does too.

I have been using the KN test from Kreverki for about two years now. I compared it with Salifert and JBL, and it shows the same results. Moreover, it has syringe titration with increased accuracy, just like Salifert, but the amount of reagent is several times more. Recently, I bought a regular drop test from them (I got tired of titrating), and it also shows everything correctly.

Well, you can't please everyone, it's great for 25. Excellent test. Off-topic. And about JBL - there's no more convenient test for Ca. In the same Salifert, you can't tell if it's blue or cyan, and the difference will already be 10-30 ppm. The only downside is that it runs out quickly. And so what, is Salifert the standard?

It's not about "pleasing." The JBL shows kN-7, which is low, we need to increase it, we increase it, measure with the salifert - 15, it's too much.

I am asking, is Salifert a standard?

For M.A. (marine aquarium) in general, yes.

Who has the Seachem tests (multitest) I am interested in the jars highlighted in red. They are labeled, for example, Reence 1mg/L NH3, NO3, PO4. What is PHreence for? Nothing is mentioned about them in the instructions.

They are labeled, for example, Reence 1mg/l NH3, NO3, PO4. What is PHreence for? These are control solutions for comparing measurements. For example, for PO4, above it is marked 1ml per liter; you take the solution from the bottle and conduct the test, the scale should show PO4 1ml per liter.

In the description of the Calcium test: there is an error, it should be 5 drops.

Very funny. It's the same calcium test from JBL. I've been using it for three months, once a week. Last time I noticed that when I added the second reagent, the solution turned blue immediately; I tried again and the test passed. Today, no matter how many times I repeated it, the solution turned blue immediately after adding the second reagent. Of course, I reread all the instructions and googled, but found nothing. I had the thought that the first solution might have lost some of its concentration, so I tried adding 6 drops. The test passed! I hope this information will be useful to someone.

I have been using JBL tests for calcium and magnesium since 2001, and I have never encountered anything like this.
