I have done many tank transfers and if the old water from your old tank fills the new tank up by a third you will have no problems filling the rest with normal tap water. Many of times I have done this with no chemicals at all and sometimes with even less water from the old tank. Another good way to help is by not cleaning your filter just take it from your old straight to your new

There is very little beneficial bacteria in the water, much better to seed with used filter media, decorations and substrate .

You could run both filters on the old tank for a while to allow the bacteria to breed on the new filter, or you could take some of the old media from the old filter and put it into your new filter. Transferring water is pretty much pointless.

I agree with DavePM. Not much BB in the water. Good advice about the filter media.
