None.

Does anyone else use anything else to help hard water?

Hard water is good for plants.

pure water you can add to it whatever your plants need. Many geen
houses use this technique as it stops the build up of salts in the
soil, and therfore prolongs the life of the soil (no need to re-pot!).

Ahhh but that doesn't apply to aquaria, since there's very little precipitate
accumulation.
