I noticed this afternoon that the water level in my pond had fallen
dramatically.

It's a 1000litre pond but it must have been down to at least 1/3 of
it's depth.

I did notice recently that it was lower than usual but we have had
nothing but rain recently.

The 9 fish (3 goldfish and 6 orfes) are doin ok, I've topped it up and
turned off the pump and filter to see how things go.

My plan being that there can only be two reasons for the lack of water.
Either I have a hole somewhere in my pond (solid plastic type) or the
pump / filter is chucking out the water elsewhere.

Any suggestions would be greatly appreciated.



What I have found, is that the liner is very rarely the culprit. When I see
a drop in water I check:

1. The water fall. Sometimes things shift about or plants grow. If I don't
regularly clean out the water hyacinth, they sometimes grow over the edge
and water wicks out that way.

2. The connections on pumps and valves. Sometimes a valve will get opened
slightly and drip out of my "empty the pond line".

3. Where the liner meets the edge of the pond. Sometimes plants or dogs push
the liner down, allowing a small trickle.

Two years ago I had an issue with loosing water. I looked for weeks and
couldn't figure it out. I finally thought the connection at the skimmer was
bad, so I redid it. No better. Long story short, but we finally discovered a
small crack in bottom corner of the skimmer.
