Hello! I am looking to start my first saltwater aquarium. I have a 35g freshwater that I am going to turn into a saltwater but I am always thinking into the future. Do you think that it is better to buy an average priced / quality aquarium and add a canister filter or spend the money on something like a red sea or waterbox aquarium with a sump, protein skimmer, etc? I LOVE the look of rimless red sea and waterbox aquarium but I was wondering if there is a cheaper alternative? The tank that I'd be buying would be about 75-125 gallons. Thanks!
