Are water changes really necessary?

Another reason I stopped using the vac to remove the mulm on the bottom
was newts and small frogs were getting killed when sucked up. They don't
survive the trip through to the tank. Small fish are injured beyond
saving. I always have these small creatures in my ponds.
Then how do you clean the mulm out? or do you leave it?
