How to do a reef tank water change

[Flash]

yup I use tap water! have been for 5 years! never had a problem! We also use tap water in the store without a problem!

i always add my water into my sump return-that way it doesn't disturb the display

I use tap water as well. I remove whatever water out of the tank. Fill up buckets with tap water and mix in the salt. Test salinity then dump it in.
I have FW tanks too and its all the same, except for adding the salt.
