| Re: Saltwater Tank beginner A reef ready tank will be drilled so accomodate plumbing for overflow and return, flow goes down pipes into a sump where you have various filtration equipment; protein skimmer, carbon and/or phosphate reactor, return pump for the main tank. It sounds like that tank has a hang-on back filter maybe? The type of filter system and light system you use will depend on several factors, one of which is what you plan to keep in the tank. If you can post a few more details about the system and your goal for inhabitants, that will help. Also, WELCOME!! |
