I have to fill my big tank directly from the tap, it's far to big to have buckets standing around dechlorinating, I'd need 300 bucket in my living room 
So, we rigged an easy way to fill it from the bathroom. (We poke it out the bathroom window and back in the living room window).
You will need a section of hose pipe, long enough to go from the bath to the tank and a "shampoo spray" shower thingy, just one of the average rubber ones you can find in "It's a Gift" for two pound fifty.
If you plug the shower thing on both your bath taps and unscrew the shower head, there is a plastic stopper fitted in there that stops the shower head coming off. Pull it out and take of the ring that screwed the shower head on. Now the end of the rubber pipe will fit directly into the cut end of a hose pipe, with no leaks.
Make sure you have the temp mixed right before you jam it in (and that whoever is monitoring the other end has it in the tank!) and off you go.
This method fills my 6ft in about 10 minutes - which is a lot easier then having to cart 40 buckets in and mixing the water by hand every time.
Add your dechlorinator and off you go.
I got the idea of using the shampoo sprayer from when we fill my kids swimming pool, we unscrew the "fits over the tap" end of it then and we found that the threads on that fit exactly into the threads on a tap adaptor that you would screw into an outside tap to attach your hose. In doing this, I can fill Bu's pool up directly from the hot tap upstairs.
It's basic I know, but if you haven't thought of it, it's worth knowing, it saved us a whole evening of work when we figured it out.
