Hello I am going to set up a 20 high as a biotope for Microgeophagus Ramirezi. I have a R/O unit I plan on using to get the water a little better than our native Cumberland River water. I am looking for advice on this project, most notably: a suitable light, plants, substrate and quality breeder of the German Blues. The tank is not set up yet so I am flexible, I was wondering if a 30 high would be better but it looks like a larger footprint is more important. I also have a 70 gallon (not set up yet) but thought it might be best to start of on a smaller scale. Thanks - trhaight

You should have a test kit to measure GH ,KH, and PH levels. You can mix tap water with the RO and aim for a KH reading of 4-9 and a fairly soft GH level , say 100 ppm or so.
I would err on the side of caution and not try to get the water softer than that as you can run into problems with PH swings.

Reconstituting RO water is about restoring some of the general hardness (GH) to the water not the declorination.
