Ok so moved out my apartment and back home I have a 55 gallon tank with stand that's just waiting to be used! Well it's in use but hasn't been properly taken cared of. So I thought starting over would be a great idea! The only things I have is my 55gallon and stand got some old lights over it t5s but want to go back to LEDs like in my old tank also have my Red Sea test kit. Now that I have been thinking about this whole setup I'm starting to think its gonna be really expensive I'm thinking about at least 600 to get the things I need to start it up. Ro unit/ sand / rock/ diy new sump/. Over flow kit/ salt /pump. That's not including the lights skimmer and pumps. Am I right? How much do u think i should budget? Just for the starter stuff
