So what do you guys suggest for saltwater test kits? I know Red Sea is basically the oh-heck-no of testing, and I hear API is pretty 'meh'. I hear Salifert is good, but I'm looking for something all-in-one like Red Sea has, where it comes with PO4/NO3/NO2/etc all in one box and I can't seem to find a Salifert one like that.
Thoughts?
