Once weekly:
Magnesium
Calcium
Alkalinity
Ammonia
Nitrate
Nitrite
pH
Specific Gravity
Temperature
I also rely on water changes to replenish things. 3 gallons 2-3 times per week in a 90.

I'm one of those guys who doesn't break out a test kit very often (once every 3 months maybe), when I do it's nothing but Ca and Alk. I should probably get into testing Mg eh?
