Hi, I've been contemplating starting a saltwater tank on my own for quite a while now. I have maintained SW set ups before but I never set them up. Meaning I did water changes and fed the fish haha. I'm more into freshwater and am fairly familiar with a wide base of knowledge due to years of experience with freshwater fish and tanks. Now I understand that SW is different, however, I'm beginning to think there are quite a few similarities between the two. Although I'm most likely mistaken. Okay, to start off with, as I mentioned earlier, I don't know a thing about saltwater aquariums! So bear with me. I'm interested in setting up a smallish saltwater aquarium this summer. To be more specific I want to set up a small reef tank. I thought that I should get in at least a few months research before I begin setting it up. I want to know how you go about setting up a tank. What sort of equipment do I need to start a SW aquarium? I mean like specific filters, heaters, ect. I know you need a 'protein skimmer' in most SW tanks. From my understanding all that does is remove excess ammonia and nitrite. Right? Also are there special types of heaters I'd have to use or would a titanium heater work just as well as any other? How do you measure the 'specific gravity' of a tank? If I understand correctly the gravity of a tank is the amount of salt in the water. Right? How do you control how much salt is in the tank? Do you add salt before you change the water for a WC or do you add salt to the new water before adding it? How do you begin to cycle a SW tank? Can you jump start the cycle by adding cycled media from another SW tank? Correct me if I'm wrong, but I believe that 'live' rock is called that because it has bacteria growing in it. So it is supposed to help the cycle. But if you add live rock to a tank without an ammonia source (fish) then wouldn't the bacteria die? Or do you not do fishless cycles in SW tanks? Haha I think that's enough questions for one night. I hope I didn't leave anyone as badly confused as myself! I'll definitely have more questions for you.
