RO/DI for Freshwater?

[JHG]

R/O water is great for fishes that require soft water / low TDS, etc. In the future I plan on establishing a South American dwarf cichlid breeding project and will be using R/O water. Ensure that you add some crushed coral to the filter to avoid any pH crashes. The blackwater extracts that are on the market are a decent additive, plus you can use peat purchased from your local hardware store, i.e., Home Depot, Kent, Canadian Tire. This peat is SUPER cheap compared to anything purchased in a LFS.

PS: Forgot to mention that I'm in the market for a reasonably priced R/O unit myself.
