So this is my first reef tank that I recently started and so for I think it is a success. I got a good deal at PetSmart that came with the filter, heater, lights net and thermometer. I already had a small 10 gal tank with fresh water fish and decided to try a salt water reef tank for the first time. I've always seen them and thought they were amazing but always thought it would be too hard and expensive lol. well I can confirm is it both hard and expensive but I think its worth it in the end.
