Test kits and frequency of tests that should be run?

[newreefer_59]

In setting up my 150 gallon reef tank, just like to get a feel for the water testing kits and frequency of tests that should be routinely run....

My first set of test results:
Specific Gravity - 1.02
Temperature 75 F
N02 - Near zero
Calcium - 500 ppm
Magnesium - 1300 ppm
Ammonia - .1
Pottasium - 325
KH - ~ 15


The additives I have been using:
Corallife Calcium
Magnesium
Marine Trace Elements
Strontium

Many thanks
