And if a person does not want to do water changes to
reduce the ammonia levels to keep them from being terribly
hight, I dont' care. It's their rock. They can do what
ever they want to, but if it's my rock, I'm going to keep
the ammonia levels from getting too high, as I want what's
still alive on the rock to remain alive.

Even if it were to cause the cycle to take longer, which I
do not believe, so what. If it's my rock, I want what's
still alive on the rock to stay alive. And I find it odd
when people don't want to try to keep alive what's still
alive on the rock.

Another option is to reduce the needed water changes by
vigorous aeration by using a venturi on the pump. This
helps drive off excess ammonia. It does however have the
downside effect of creating salt creep, and putting more
corrosive salt into the air.
