Theres only 1 problem with "leave the tank alone unless fish are dying" and that is, fish were allowed suffer and die. While deaths in this hobby are gonna occur, we should at least do our utmost to prevent them.
The ONLY way to prevent them is to test water daily and if the ammonia or nitrite are above 0.25 to do a large water change/add prime to detoxify.
If the nitrite level is through the roof, it will kill them.
