I saw the protein skimmer and it looked "very used" I didnt see the UV. Did you see the RO set up go for 30 dollars or so. I was tempted but even if it needed new membranes it was still a good buy.
Ming: If you want to give Ammannia senegalensis a try just let me know. I think it will do alright. I may turn green but the tops will likely turn pink. Just give me a couple weeks and I will send a couple "test" stems your way.
