In most cases the pond we will be cleaning actively has Fish living in it. We will set up a temporary holding pool which we then transport the Fish into with some of their existing water whilst also letting the pool top up with some fresh water which we treat with a tap water conditioner. At the end of the day once the pond has been cleaned we will pump the water from the holding pool back into the pond and net the Fish back in. From the Fish’s point of view it was simply a brief holiday!
