AFA swapping the rock out well if there's a severe algea problem because there's an cumulation of detritus then by all means cook or boil the rocks.

I also have to ask how many people actually experience OTS? I have seen plenty of tanks that are over 10 or 15 years old with no problems without cooking rocks, without bare bottoms, without deep sand beds (Not nec. everything I stated).
I have also seen people with tanks that are 7 or 8 years old suddenly crash and they blame OTS? Is that a proper conclusion? Probably not. As cheeks asked, what is OTS? Then what causes it...
