Test Kit for Reef?

[Simmy]

Hi there, looking to add corals to my system. I've done a search and I've pulled up older threads for test kits. I was just wondering what test kits today you are using and recommend for a beginner looking to add corals.

I already have the AMMO, NITRITE, NITRATE, PH kit from API which I think are sort of hard to read but are ok.

I know I'll need CA, MG and ALK test kits, but which ones are the best brands that you've used?

Your input would be most valued!

Thanks!
