What R/O systems do you use and recommend?
Im interested in getting an R/O system, not for my planted tank, but for increasing the hatch rate from my 2 discus pairs. As it is, the eggs from spawn are fertilized, but calcify thus preventing hatch. Im sure that what is used for a planted tank would be just as good ( just as applicable ) for the raising of fry.
Out of tap:
My pH is 7.4
KH 3/ GH 5
TDS fluctuates between 115-125 during year
Goal TDS ( this is the important #) 70

SpectraPure 90GPD Refurb unit. I run two of these, man are they amazing. My tap water TDS is currently around 260, GH is 13+. TDS from RODI is zero, as expected, from both units. Remineralize to parameters you want, 70 TDS is pretty soft! I think @FreshPuff
is probably talking about these same units.
Edit: This is what I run - http://spectrapure.com/RO-RODI/RODI-...PD-RODI-System
I'm not seeing their refurb offer anymore, might just be missing it. It was this unit, but for $129 and no warranty beyond 30 days.
I would avoid systems like the RO Buddie - cheap up front, but cartridges do not last long and are way overpriced to replace. I imagine you'll be replacing a lot of water since you're doing multiple water changes per week, so this should be a major consideration. The Spectrapure units use a standard cartridge that be used across many lines of RO units, last a long time, and aren't terribly expensive to replace.
