Rob, cooking the rock doesn't make it "dead" rock It's more like letting it rest in the dark, under heavy skimming to use up any nutrients that are contained in the rock, blow off/out any debris, kills off any unwanted algea (including coraline) but it won't kill benifical bacteria. It souldn't smell any worse than your present tank does now.
This is a list of what was tested in my last health dept. well water test..............
pH, Alk (CaCO3)[hydroxide, Carbonate, Bicarbonate], Flouride, Chloride, Sulfate, Nitrate, Hardness (CaCO3)[Caronate, Noncarbonate] Calcium, Magnesium, Iron, Maganese, Total Solids [Suspended, Dissolved], Color, Turdibity then there is a "other".
Hope this is helpful.
I guess if you looked on the bright side.....you could alwasy start breeding sea hares. I don't think they'd starve :wink:
I really do hate that your having so much trouble.
