	I made some enquiries about RO and chloramine, and was given to
understand that a good RO setup would remove it, but that a low-priced one
might not.

	Baensch suggests pH 7.0 to 8.5, and GH 10 to 30.  My guppies do just
fine at pH 8.0 to 8.5, and GH at 20 or more.

	I think it would be a good idea if you read the material on the Krib
and elsewhere about water chemistry.  In short:  "Hardness" is Ca++ and Mg++,
so sodium bicarbonate won't add any.  It will add "alkalinity" or "KH".

	I would use powdered CaCO3, at about 200 - 300 mg/L.  It will take
quite a while to dissolve.
