Actually, there are some very good reasons to use dechlorinated tap water. No bacteria, you can adjust for temperature immediately, and in most regions, it has much better pH control than RODI does.
If you use RODI, you need to warm it up and add a pinch of bicarb to raise the pH.

I trust Jay on this subject. I will be doing a tap water fw dip that I added PRIME to. That will dechlorinate the water but leave the other benefits in it. I am not going to use clove oil yet - if this is a parasite it is likely to come off in a FW dip (which is easy to perform) and no oil is needed. If it does not come off I then need to decide to either remove it or let it grow on there and hope the fish can survive w it. I have not seen him breathing harder than normal (including previous to this showing up), his behavior has not changed including eating. So I am not in a rush to sedate and remove...yet.
