Large aquarium question

[Dan J. S.]

Do large aquariums (750,000 + gallons ones), like Chicago's Shedd, change
20% of their water like any of us? I am curious. It would seem to be
extremely expensive (just the salt alone) to do this.

What a great question!
You can call and ask either a freshwater or marine aquarist during certain
hours.
Just give them a call (if your in the area) and find out what specific hour
they accept calls.
Their head freshwater aquarist (Bill), helped me years ago when I had what I
thought must have been fish TB, but had never heard of it until I did some
researching.
Sure enough, it was. He helped me a lot and spent a good deal of time with me.
Nice guy. Wonder if he's still there. = )

I remember an article several years ago about the problems Disney was having
in Florida with a very large volume of sal****er with high nitrates. There
were environmental concerns relating to the disposal. I don't remember
hearing of any solutions, although I'm sure it was solved somehow.

I would guess that they have high power filters they clean and rejuvinate
the water to exact chemical specs. The ones that are next to the sea, has a
continous flow of fresh water.

This is true for SCRIPPS and the Seattle Aquarium, I know. In fact, both of
these places sell filtered seawater for much cheaper than you can make it.

The Seattle aquarium has it's output into the Puget Sound as a slamon
ladder. Every year, salmon come back to breed at the aquarium, where they
are reared and released.

Blue Planet (NW England) have a 2.5 million litre tank and they don't
change the water at all. They have huge filters and (presumably) have
worked out how to balance the life cycle so that things stay balanced.

I had a back room tour of the place when it first opened and I asked
*lots* of questions !!

Ugh, seriously nasty web site !! I'm not sure I would have been
convinced to visit if I'd seen that first !!

Shame, good aquarium, lousy web site.
