It also takes longer, and waist salt.

The way I do water changes, is I make the new salt water slightly saltier
than the aquarium water, then pump the new water into the aquarium into a
sock at the bottom of the tank. The new water stays at the bottom, and the
old water goes over the overflow. I also hook a hose to the side output
valve of the return pump plumbing, so I can at the same time, pump old
water from the sump down the drain in the bath tub. Salt water works great
for the septic tank.

salt isn't particularly good for a septic tank. figure if you're using a
bucket of salt in a year, and it all goes into the tank, where does it go
from there? a lot of time it's still in there, or in your field, and it
doesn't do any good for the bacteria that should be in the tank.

i use mine for killing weeds in the driveway. however, you have to watch
where the salt will migrate to during rains. in az, that doesn't happen
frequently.

So the water in the aquarium does not drop, except for a tiny bit because
there is less water flowing in the tank to keep the water higher than the
overflow. I can do a 50% water change very easily this way.
