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

I used the API tapwater filter for the life of my 35g nano (about 1.5 years), I've never really had any issues. Just get a TDS meter and replace the filter once it shows above 1 TDS (typically 9 months or so).

That being said though, I switched over to true RODI when I got my 90g up and running. You can connect a hose bibb to RODI, just make sure that the hose connector is tight.

Our water in Vancouver is so good (I measure 15 TDS in Richmond consistently) that I wouldn't be surprised if some people use straight tap without issues.
