Just bought one of these pumps and 11m of tubing to do my water changes on my main tanks.
A cheap Sunsun pump and standard 16x22mm tubing; total cost around £40.
Meant to do it ages ago but I've since sustained a lower back injury so lugging lots of buckets of water about is a no no at the moment for my 200L and 400L FW tanks.
To empty I simply sit the pump in the tank and pump in to the sink or outside through the 11m of tubing.
For filling up I put a bucket in the sink, fill it up and leave the tap running at the correct temperature and set the flow of the pump (it's adjustable) to match the water flow from the tap and attach the outlet to the tank and let it fill.
Every-so-often I will add some conditioner (Seachem Prime) and any other additives to the water as it's being pumped back in.
Fortunately my fish (Malawi Cichlids and Tanganyika cichlids) like water direct from my tap as it's quite hard. Couldn't really do this with soft water or SW tanks.
I needed a much a bigger pump flow rate compared to the tap flow rate due to the head of water pumping it up in to the tank.
My tap is around 600LPH but the pump is 1600LPH (but adjustable.)
