Need help something's wrong

[CableGuy86]

Ok idk enough about this rodi stuff any suggestions on what I should get. Looking for cheap, easy, and possibly portable. Not sure about this 4 stage value/plus or 6 stage.

Also I would like to add a skimmer. Looks easy enough for the nano biocube. Any suggestions here?

Lastly ur telling me this is better and more accurate than the swing arm? I may run and get this today if so

RODI stands for reverse osmosis deionized water. You run your water through several types of filters until it has zero total dissolved solids (TDS). This is the best type of water to mix with your salt mix.
