Stocking limits.... regardless of compatability issues.... has nothing to do with water parameters. It has everything to do with how much oxygen the water can hold and wether or not they suffocate.

SW holds much less oxygen than fresh water. That is why stocking limits are much less for salt water. It is hard to get enough gas exchange naturally in our tanks. We can rely on mechanical means to get more oxygen in the water.... but then when the power goes out for 4 hours they all die. Natural reefs actually go hypoxic at night and so do our tanks. Oxygenation by photosynthisis during the day is the biggest contributor and at night oxygen levels can drop drastically.

It is all about the rate the fish remove it and the rate at which it can be replenished. We can all build huge bio filters to process the waste from 10 tangs in your 60g tank.... and they would all suffocate with in an hour or two.

isn't the amount of dissolved oxygen a parameter but good point

How often do you test for disolved oxygen? Can you tell me where yours should be right now?
