For the OP: I've been trying to answer that question. Good information in this web series. http://m.youtube.com/watch?feature=relmfu&v=xifweoA0N4Q
I think SW
takes a lot more finesse and knowledge. For example, when doing a water change, depending on how you mix the water, you may need to cure it for a few day. In FW
, you can just treat and change water. Also, equipment and fish are much more expensive. Some fish may be wild caught and if you are like me and don't want to get wild fish, your options are more limited. You can't get tank raised SW
fish for $1 - at least not in my area!
Hope this helps make your decision. Personally, I will stick to FW
for a few more years!
