I'm not sure if this is the right place for this question... but here goes. I'm living in a high-rise apartment in Houston. I've got two display tanks in my apartment, but there are also large storage units available in the building's basement. They are climate controlled, secure, and have power and lights. I'm thinking about setting up a small workshop for myself down there where I can frag
corals, run a few growth tanks, make salt water, and do other DIY
fish projects. The only drawback that I can see is that there isn't any running water. It is just a quick elevator ride from my apartment, so I can bring water back and forth, but I want some way to do RO
filtering down there. Has anyone ever seen an RO
unit that can run on gravity, maybe with an elevated basin? There isn't really a good place to do it in my actual apartment, but plenty of room for something down in the basement. Any thoughts, on the RO
unit or otherwise?
