I just started a 10g sw tank. Its got 1 clown fish 2 damsels and 1 hermit crab. Its doing really good so far. My question is this, live pretty close to the ocean and i was wondering if i could have started this tank using real sea water. I understand about parasites and all that but, it just seems more natural to me and i dont see why it wouldnt work. I used Instant Ocean. I was just wondering about this..
