i think tap water is ok depending on where you are...
my lfs has amazing tanks and they use tap water for all of it... just prepair it few days in advanced..... im using tap water and it hasnt been any problems...
like i said.. i think it completely depends on where you are.. but if you are not sure, run a few tests on the water and see if all the levels are safe.
