Not understanding the syntax of the question, I think I understand the gist of it. It really depended (cuz I no longer perform w/c's) on whether it was my own tank or a customer's. Once I got to using it, I always used RealOceanTM, so no worries about anything other than matching temperature.
Before that I had two trash cans (the 33g ones) that I lined with black plastic trash bags (just plain old bags, no scent or anything like that - bad juju). Those had a powerhead dropped in 'em and were kept tightly covered in the garage. A day before I wanted to do a w/c, I'd put one of my submersible heaters into its handy-dandy PVC tube (otherwise it could melt the plastic) to bring it up to temperature. Then, I'd take a powerhead and pump some of the water into my 5g jugs (I bought some from Sparklett's, WITH the caps, they were great for using with customers) and do whatever change I wanted to.
To make it really easy, if you're not cheap like me, then buy a pump to do the changes (external pump would be the preference).
Does this answer your question?
