I too have R/O like water. Used Onyx in 35 gal. At first it raised the KH to
7 but with weekly water changes it slowly came down till now at 6 months it
is 3-4. At first it looks really cool, just like the bag but after awhile
pretty much can't see it just like other substrates ;-> I do like it. It
treats tender roots very gently. I have a beautiful very narrow leaf sag
that is picky and would only do well for me in dirt. It is now growing very
successfully in Onyx.
You might check the archives for Tom Barr's info on use of peat with Onyx to
control the hardness.
