Use hose and water butt to top up aquarium.

With this system I can get 100 liters out and 100 liters of clean rain water back into the tank under an hour with no carrying buckets or spills. This is ideal for fish that like softer water. Test and use some tap water so that the water dies not get too soft. We need some hardness for buffering to avoid big ph swings. See other videos on the channel for more details on this a low cost easy way up do large water changes.
