Hi everyone! We just got a 105 gallon aquarium from another military family that is PCSing soon. I figured we'd start our salt water hobby now since my husband and I have always wanted to. Of course, I chose when we're living in Germany and don't have very easy access to a store with salt water fish or corals. Oh well, that's what the internet's for, right? Anyway, we took a break from fish when we started having kids, and never had a salt water aquarium. Needless to say, I need all pointers out there. I prefer cycling new tanks with some gravel from an already established tank, generally from a friend or local store, however there aren't any salt water stores around. Can I use gravel from a fresh water tank to do this? Basically, any and all pointers on starting and maintaining a salt water tank are welcome. As well as reliable online stores for fish and corals. Thanks!
