which test kits to buy?

I use elos and like them , if you have lps or sps then you need to keep an eye on cal ,alk , and magnesium . Some people dose iodine but most don't as its replaced with regular water changes , a copper test is only needed if you dose your quarantine with copper and then get the same brand as what you are dosing . Oh and want your coralline algae to take off make sure your magnesium is up and it will go nuts.
