This is not a very good idea simply because there's a better way of lowering GH/KH. Why not just use an RO filter? That way you have full control.

The other issue is whether you're lowering the KH/GH for the benefit of the fish or of the plants? The vast majority of plants don't care about KH/GH.

Cheers,
