What's the best way to do RODI in an apartment?

You can get RODI units fairly cheap, and they don't need to be permanently installed. You can get adapters that screw into your faucet, so you can store it, and then take it out and use it when you need. I can't see that tap water filter working nearly as well as a proper RODI system, but it's better than nothing. On a tank your size, you could probably get away with weekly five gallon water changes, depending on your bioload. If that's the case, most Superstores sell RO water, and so you could just fill one jug every week and make do with that.
