This will be my second try at saltwater. About four years ago I sold my first reef setup it was a 75 gallon rr tank that I had setup for about 5 years and all was well but 2 little kids took all my spare money. So my question is what would be a good tank to start with, biocube 29 , Marineland 60 gallon cube or Marineland 75 gallon. I know a lot has changed in 4 years so just wanting advice and I know bigger is better but not looking to spend a fortune and already had the 75 so may want something different. Also afraid of the 60 cube because the stand may be too small for a big enough sump. Thanks
