Can Anyone Recommend An Excellent Test Kit?

[Navarchus]

I have a good experience with Elos, Salifert and Red-sea.
I think every brand has some kits that are good and other that are not that good.

For example red sea test kits that are rated as pro are very nice, but the other test kit are very armature.
I had a very bad experience with Salifert alk and iodine, and a very good experience with Elos alk and RedSea iodine.
Salifert CA and MG are excellent buy the strontium not that good, Seachem strontium is very good.

I would recommend:
No2, no3, nh3= JBL
Alk, ph, po4= Elos
Ca, mg = Salifart
Str = Seachem
Iodine -= red-sea pro (also good for alk and ca)
