I have very soft water because I use a reverse osmosis system. I harden this water a little bit and use fertilizer in combination to CO². Not very much, but together with the excrements of the fishes it seems to be good for the plants.
And I only have plants, which are robust and don´t need much light like vallisneria, anubia, nymphaea lotus and so on.
