Ro/di

[Crooked Reef]

I'm buying my first RO/DI unit. I'm looking towards the spectrapure refurbished models. They currently have a 90gpd 4 stage for $125 or a 5 stage 90gpd for $189 or a 4 stage 180gpd for $199. I will only have a 90 gallon tank set up so I don't really even need a 90gpd. Are the higher gallon per day units more efficient and produce less waste? Do the resin cartridges last longer if they have more stages to the unit? I like the idea of faster water when I am making it.

How "clean" is your tap water?

Does this help?

My lfs who is less than a mile away predicted 9 months on a 75gpd BRS model they sell. I live in St. Louis County, pretty big area of that matters.
