George,
That's rather an odd reply from someone with all your
stated experience, while your statement is true the changes are
insignificant and would take along time to show in a salt water system
unlike fresh water.

PS. I've been n the hobby for more than 50 years.

That has been the assumption for a long time by a lot of aquarists. I'm not so
sure that it is insignificant. I guess I'll have to wait and see how things
change in the hobby over the next few years. Remember, things have changed
tremendously over the last few years alone. We are finding things ouot all the
time. I'm still open to the suggestion that it might be insignificant, yet my
own experience suggests that it may not be.
