test kits question?

[unsane]

I have a bunch of these Hagen-nutrafin test kits, and the color charts are just making my head spin. Are there any kits out there that are easier to red I cant tell if my calcium is 400 or 4000, my phos is 0 or 50. I ask my wife and she says its different than what I say my kids say different than me too. I need something with straight up results.

I like the red sea calcium test you add the drops until it changes color. Pink to orange no inbetween colors very easy

Aquarium Pharmacuticals are good. I use them. I've also heard good things here about Salifert kits.

I like the Salifert kits. Titration endpoints are fairly obvious, and you don't have to count drops.
