Hi everyone! I finally decided to start a saltwater tank. I have kept freshwater tanks for a couple of years and wanted something different. I am completely new to the saltwater hobby. My question is where do I start? I Have a 55 gallon tank that is not drilled that I have been using to house a Flowerhorn. I am going to use this tank in my setup. What equipment do I need to get started? Do I absoulutely need a sump or can I use a canister filter? Im sorry for such a newbie questions but I want to do this right and be successful In my first saltwater tank. Im not going to lie its alittle overwhelming at first: Thank you!
