Tap water calgary

[abcha0s]

The problem is with evaporation. If it was just a question of water changes, you might get away with conditioning your tap water, but top up is a different story.

Only pure water evaporates. All of the TDS from the top up water stays in your system.

Anyways, if you want a stable system, you have to control what goes in.
