Hi everyone, I live in Manhattan and I would like to add a saltwater aquarium to my home. I figure this will be a fun I am seriously considering purchasing a silver or white Red Sea Max 250 with a Chiller. Been reading a lot about this online. I like the size of this unit vs. the 130D. The other option is to by it a la cart. Creating my own tank and filtering system and heater which will give me more flexibility. I plan to buy one soon but i just started to do my research. This is an expensive venture but I can handle it and I feel the rewards outweighs the cost. I figure my niece and nephew will love it too when they visit. My first question is do I buy a kit or really learn this by buying everything separate? the second more simple question is where do I get the water? from a fish store or my tap water and just add chemicals to it. I do understand that this is a long process and you need to have patience for this type of hobby.
