Reverse Osmosis water for our plants and fish

[R. Mara]

We have been using Reverse Osmosis water for our plants and fish and have experienced trouble due to the inherent acidity of the RO water (pH 5.8). A company recommends using mined silica clay. What is it and where do I get some? I was told: "There is also another product on the market now that is supposed to work wonders with RO water. It is actually a mined silica clay that contains 72 micro-nutrients". Any comments or suggestions will be appreciated. Thanks, R. Mara rmara@blazenet.net

A pH of 5.8 is to low for fish but is perfect for plants. pH is the problem when trying to do both.
