Not to diverge on a tangent, but these type of water parameters makes using ADA aqua soils a possibilty for us blessed with very soft water. Before, I thought too bad, I can't use the ADA substrates as it softens the water. Perhaps this helps explain why the Amano's soil substrate grows plants so well. They are happier in that low KH/pH environ.
Ps... thanks for the feedback Craig and others!
