Just to clarify, it is OK to use tap water to clean equipment. It is not OK to use it in your tank. If the
LFS is closing I would check Wal-mart to see if they have a water machine that people refill their 5 gallon jugs from. Although this is only
RO and not
DI it is far safer than using tap water. Don't stress too much about the gross water form the sand. It will clear up.
