His summary:
Magnesium:
I do not know why I keep trying Red Sea Mg Pro. I have given it many chances and not once have I gotten a reliable number. I've gotten very low and very high results in the past and now. Of all the kits and places this is one that I trust the least and most frustrated with. I've been happy with all the other Red Sea testing kits. This makes the Calcium, Alk, Mg bundle to me to be not worth it.
Elos Mg kit was also off but on the lower side. It could be the 2 phase approach which I do not like at all. Way to much room for error. Elos PO4 Pro kit was awesome and Calcium and Alk in line with the others. So, this was kind of disappointing.
Salifert. This really just solidifies Salifert as that overall winner here. It's nailed it in all three of these parameters and many others. It may not be my go to for everything but I know I can count on Salifert if I ever needed too. If someone wanted to stick with a single brand for all tests Salifert is it. more then enough accuracy, high enough resolution, and consistent. Could not ask more of a hobby grade kit. I would even stack it up against the "professionals" (ahem AWT...)
