Sera test kits? Any good?

[frags75]

Looking for a new test for cal and KH. Are they any good? Has anyone used them? How do they compare to API? Need something reliable and pretty accurate without spending a lot. Input and expieriences please. Thanks.

They are cheap, easy to read and good for a quick check. But they aren't very precise. Ca reads in increments of 20ppm and alk in increments of 1 dKH.
I never used API, so I can't compare. I use Salifert and the Sera results are generally in line with Salifert.

Cool thanks. Anyone else have thoughts or expierience with these?
