Well, you can get updates/alarms from your tank, you can check compatibility reference material when at your LFS shopping for a new fish or invert, you can scan barcodes for price checks at your LFS and find it cheaper online, you can keep track of your tank stats on one of several available apps, you can call Catherine for photography advice, you can order Biff's cheato online or over the phone, you can take a video of your tank and post it to youtube and then post the link on living reefs, you can surf LR (although that would be much nicer if Ian would install tapatalk! ;) ) and probably a host of other things I can't think of at the moment. But see... it IS like spending money on your tank. :mrgreen:
