Best Kit For Water Changes

I'm thinking about how I'm going to do water changes on my 220litre tank when its set up and want to find a cheap, pain free method of doing them.

As such I've been researching water change pumps but am rapidly realising these still require copious amounts of water to be moved about the house which sounds like a lot of effort for what should be an easy essential task as part of the hobby to ensure the best possible environment for the fish.

As such I'm therefore wondering about siphoning the water out into the garden... or toilet if needs be... and filling the tank from my mixer tap attached to a combi boiler system to put same temperature water back in really easily.  This could be achieved with one of these:

What do you think?

Google DIY python. The actual pythons are American but lots of people have created their own versions.

@Littlefish I like the idea of using the filter pump to assist things but I don't think my filter has the same feature you are describing.  I could only do this by taking the filter hose off and putting a new one on... I think the hose would wear and possibly the 'watertightness' of the seal would degrade quickly.  I'll have to see how long it takes to drain using the siphon and go from there.

@Sue I recognise the python and have now googled the diy kits. It is becoming clear that the easiest way to fill the tnnand is indeed by attaching a hose to the tap.  The part I put a link for below will do this.  If I can use the hose to start a siphon the other way with the tap adaptor removed, and it doesn't take too long to drain, then that should be all I need. I never l liked the idea of all the treated water wasteage when draining the tank when using a python so it will be good it I can avoid this if possible. 

@Helen  I'm thinking of using garden hose with the adaptors linked too so long lengths won't be a problem. I found a kit with 10m hose on a little compact reel with a handle to wind it in which will be useful.

Do any of you have any experience trying to drop the water level in a take using a siphon on garden hose diameter tubing? Interested to find out how long it is likely to take to drain say 50 litres from a ground floor tank to a garden drain.  Presumably the siphon tube could go out over the window sill and out that way as long as the end of the hose is low enough compared to the tank?

I still use buckets & manual syphon for the smaller tanks, and the Fluval FX filters are the only ones I have that have the extra connection for water changes, so my dwarf puffer tank is also still done manually.
I don't have any experience of using garden hose & tap connectors for water changes, but I would have thought that 50L wouldn't take long.

You add the dechlorinator to the tank before starting to refill it. It used to be said that you should dose for the whole tank volume, but apparently that only applies to Seachem Prime, it's just that everyone assumed all dechlorinators were the same. But all the rest should be dosed for just the volume of new water.

Interesting. According to their website they say

If adding directly to aquarium, base dose on aquarium volume.

But I suppose it depends on whether they keep the website up to date or not.
