Hey guys. I'm John. I've been having aquariums for over 20 yrs but just bought a Biocube and am gonna try my hand at Saltwater for the 1st time so I'll probably be leaning on you guys hard, bare with me. At present I have a 75 gal freshwater that's well established. If I can help anybody with that feel free to ask and i'll try and do what i can.
