I recently purchased a used 29 gal
biocube. I would like to make it a saltwater tank. I have never done this before so I have two issues. I'm not sure everything is with the tank that should be since it's used - I know the light ballast is missing - do I have to have that since the blue lights still work wo it? There is a regular aquarium heater and the two things that hook to the back wall that looks like what the air blows through and there is a clear plastic divided box that looks like maybe it's the filter. Is there anything missing?
Second - I just want a real plain tank with white sand on bottom. I hear you have to have live rock??????? I don't want anything in the tank that shows except for sand and fish. Can I fix it like that? Thanks for any help and I need a lot (lol).
