I am wanting to check the calcium, alkalinity, and magnesium in my tank. Ive been doing research and seen Red Sea offers a test kit. Is that a good/accurate test kit? Would it be better to get individual test kits from another brand?
The Red Sea Pro is fine. I like Salifert, and while either uses the same technique
and style of testing Ca, the Salifert is more cut and dry easier to
understand leaving nothing to misinterpret. Just discovered this as my
new Salifert Ca kit was inaccurate and being refunded, I opted to try the
Red Sea Pro Ca kit instead. They're both good. Is that the Red Sea (Pro)
that you're talking about?
Any kit can be off, and I believe the newer Salifert offers a sample solution to check by.
