I am not sure how accurate you API test kit is as I only use Elos and salifert. If you're near Jl you could go in to get a water test... If you even care about it.

But if you're happy with where your tank is then I wouldn't worry about it.

API is OK for calcium. I always got reasonable values using it. My main issue was losing count of the drops! I wouldn't recommend the Seachem calcium test as the color change is hard to see (although I like that it uses a syringe for the titration so that you do not have to count the drops).

John Coppolino, a well known hobbyist in the US, only tests alkalinity in his amazing SPS tanks.

IMO for reef tanks that consume substantial amounts of calcium, testing for alkalinity and calcium is very important.
