Sorry to hear of your plight man. Stuff like that really sucks... hopefully you can get the work out of him!

Have you considered breaking down to less tanks? You do have an awful lot of tanks... and it's likely that when you get a saltwater setup going, you'll want to spend less time doing maintenance on your freshwater setups and spend more time gazing at your slice of ocean.
