go to the public library as they have salt water aquarium books from beginer to advanced. also ask alot of questions on here. first you would have to get things together like salt to mix with water. test kit the basic saltwater master kit from API, there is many different test kit manufactures out there just API is one that I use for the basic tests PH,Ammonia, Nitrite and nitrate. If you get into corals you will need other test kits also. you need to get a Protien skimmer you can use an air stone driven one or a nano skimmer look on here, other forums for saltwater aquariums. and Ebay just remember to ask on ebay if they ship to Canada before bidding. I have seem a few skimmers on here for a great price. Watch for live rock on here also once you have the water in your tank that is, you can try and put a wanted for what you need and see what the responces are. Best thing you can do is read as much as you can and ask alot of questions.
