5 stage or 6?stage?

Depends on the kind of water you are trying to filter. The water going into my RODI has a TDS of around 30 already, so I got a 4 stage which does the job just fine. A 5 or 6-stage system is better for water with high TDS, hardness, well water, or other contaminants like chlorine or iron. The more stages it has the more carbon, sediment filters, and or DI resin are in the unit.

This is straight from the BRS website.

"4 Stage RO/DI Systems - Perfect for city water that is treated with low amounts of chlorine, or well water with very minimal contaminants. Four stage RODI systems are a great solution if you only connect your RODI system temporarily or have little space to dedicate to storing a RODI system.
5 Stage RO/DI Systems - Our most popular systems handle common impurities found in well water along with most types of city water treated with chlorine including small amounts of chloramines.
6 Stage RO/DI Systems - If you are not sure what is in your water, or it contains excessive amounts of TDS or hard to remove contaminants like chloramines, phosphates, nitrates, silicates, etc. The BRS 6 Stage systems are designed to effectively treat any water your home may have prior to using it in your aquarium. The Dual DI stage helps with the hard to remove ions like ammonia, phosphates, silicates, etc. "

I have a 180 and also use the BRS. It's a 150 gallon per day 7 stage. My incoming tds is pretty low, but my water company puts a lot of stuff in for treatment so for piece of mind I went with that one. I've put 100's of gallons trough it and I'm still getting just 1 to 2 ppm before the Di stage and 0 after both of the DI's. Couldn't be happier. Make water fast as well.

Man, if my tap TDS was 30, I'd find out what's in it and not even use a ro membrane, maybe run it through a sediment, a few carbons, and use it all.
