What to use in place of RODI in a pinch?

[larryag59]

My small tank has been cycling for about a week.  I started with purchased seawater, but now evaporation has set in and my RODI unit has not yet arrived.  Adding more seawater will raise the salinity level, so that's probably not a good idea.  I only need 2-3 gallons, as it's a small tank. Any suggestions of what to use in a pinch or other wise how to resolve? Perhaps distilled water from the drugstore with conditioner added? Advice much appreciated

Distilled will be fine
