When it is left outside the water and salt crystals
form, then serious deterioration occurs. Tough I
have an aluminum rod that is in the sump in a
position that it is in and out of the water, and yet
it has not deteriorated any that I can see. It is
encrusted with coralline algae, and other encrusting
stuff.

Try it with aluminum foil. Stick a piece in your
sump and pull it out, let it sit in your sump, just
outside of the water and let the drops of salt dry.
Give it a few days, and you will see holes in the
aluminum foil. Then stick it back in the water and
leave it submerged. Also at this time ad a fresh
piece of aluminum foil left completely submerged,
and watch what happens. You will see that there will
be no more deterioration.

Also, in case someone does not know, you can use aluminum in salt
water, and it won't corrode, as long as you keep it under water.

Does not dissolve, even slowly?- Hide quoted text -

Yea ****ing right, like there is on ly one grade of aluminum and most
grades of aluminum that are corrosion resist have alloys of copper as
part of their mix.dumbass assumptions on waynes part again folks.
Aluminum does not belong in water expecially salt water unless its of
the marine grade with copper added which would be 110% contrary to
what is normally follkowed and [preached on about adding any metals
except perhaps stainless in a SW system and even with stainless there
is some alloys which will rust and others that will not. Listen to a
dumbass and use aluminum wire.duh!
