Ok guys, I finally broke down and bought a RO unit from Aquatic Reef Systems. (For less than my bugeted $150, yay!) It's due here on Thursday. I'm going to use a faucet adaptor and hook it up to a sink. The Hannah TDS meter reads 46 for my water... since I have a 7g nano and don't plan on using the RO unit for anything else, how often do you guys think I should change the filters? Once a year? With the TDS so low, do I need a DI unit? I assume the RO unit will come with instructions, but any tips on what and what not to do? Thanks
