Need some help!!

I have put together a letter that I will be sending out to companies within our hobby to solicit support for the Science Center's tank. Since two minds are better than one, I was wondering if you all could help me compile a list of companies that I should contact.

Here is who I have so far:

Salt Water Empire - Fritz indicated to me that they would donate if we asked nicely with a letter.
Euro-Reef
Coral Vue
Sunlight Supply
Liveaquaria
Marine Depot
Digital Aquatics
Neptune systems
Tunze
Hydor

Thanks for the help. As names are suggested, I will add them to the list.

For which tank? Science Centers? You could try Blue Zoo Aquatics too

Yes, it's for the Science Center's aquarium. I'm going to stick to dry/frozen goods for now.
