It was either that or teleportation, and since you dont work for hplabs, the answer had to be a modem. >Now, about "pure" seawater.

Do you think there >will be a problem with opacity? Well, seawater in the ocean is a living thing. It has phytoplankton and zooplankton and god knows what other living critters in it. When you confine seawater, some of the organisms die off, hence the cloudy color, its probably a bacterial bloom. Hate to be a downer, but there are also parasites in that stuff, and treating the seawater with a ditomacous earth filter and possibly UV light or ozone might be a good idea. Now, I've never done any of this stuff, but this is a capsule summary from what I've read. What you are proposing HAS been done though, find a copy of Robert P.L. Straugn's _The saltwater aquarium in the home_, wherein he describes his experiences in the florida area. -- "...and the morning sun has yet to ride my hood ornament" richard@gryphon.CTS.COM {ihnp4!scgvaxd!cadovax, philabs!cadovax, codas!ddsw1} gryphon!richard
