Accuracy of the Red Sea PRO test kits?

[blackthunda77]

I just got these test kits. I got the Mag, Alk and Calcium as well as the phosphates. Does anyone have any experience with them? I was testing high in everything except the phosphates. Alk around 10 when i have not been dosing anything, calc at around 560 and mag around 1700. Again, not dosing anything. I found an issue with my IO salt mix. Mag was 2200! along with high alk and calcium. I was wondering is anyone else has compared the results of this test kit to a more dependable one like salifert or hanna.

i have red sea cal and alk test kits along with salifert and hanna checkers and i have compared them all against eachother. they are all in same ball park range.
example: last test about a month ago

R S cal:420 alk:7
Sal cal:440 alk:7
Hanna cal:436 alk:7.15

Have been using the red sea kits for a few months with no problems. Have you compared to another test kit or taken a sample to your LFS?

thanks, that's a little relieving. I just returned my kit with new ones. hopefully these will be more accurate.

My Red Sea kit gives results very similar to my friends Salifert kit.

I would choose Red Sea though because they don't make you buy the whole kit again because you quickly ran out of "Magnesium Solution B" or something. They sell titrant separately.

I'm going to mix up some stock solution to test. I wish they made small packets of mag, calc and all solution to test against like they make.for ph to calibrate probes.
