[ken s]

What are essential tests for saltwater tanks?
so far i have come up with: (reef tanks)
Salinity
pH
Ammonia
Nitrites
Nitrates
Calcium
Phosphates
Iodine
Are there any more?
just wondering...

that is pretty much it. If you use tap water i suggest testing for some heavy metals like lead and copper.
