Test kits, which do you use and why?

[Acronuts1]

I know the importance of testing our water. Yet I am only a product of what is available at my local fish stores.
I currently use the following TEST KITS:

AlkALINITY - Seanalysis by Natureef
Iodine - by Seachem Labs
Phosphate - by API
Ammonia,Nitrite,Nitrates,Ph, and Calcium - by API

The more I get into the hobby, the more exotic corals I buy. I want to maintain the best in water quality and protect them. Are these good reliable test kits?
I don't mind paying for quality as long as I am going to be relying on accurate results.
Can you all advise on what you use, how much, and where I may order it via the web?

Thank you

Salifert test kits are really good.

I tried the Seachems but too much guessing involved IME.

I used Salifert kits for years. Salifert was always the number 1 recommended kits (along with LaMotte) and both are excellent kits.
That being said I switched to API kits a couple of months ago. They are much cheaper and acoording to alot of people, just as accurate as the Salifert.

I use API for Alk,Calcium,Phosphate and Nitrate. I still use the Salifert Magnesium kit.

I'm using API for more or lest cost issues. I find them accurate enough. I also have a Red Sea Magnesium kit that is OK as well.

For ultimate kits, I would go LaMotte or Elos. Heard very, very good things on the Elos kits.

I use Salifert and Hach. They've worked reliably for me, so I've had no reason to change.
