The top of the pot is just above the water level :) I shall leave it until the flowers die off. The water is looking clearer today. I can see the first shelf and not just dirty water

The pond water is clearing up nicely. I have noticed however that their has been a drop in the water level. I cant say how much. I'd have to top up at weekend to a level and see if it drops below. Now I pulled the liner up on the falls and its wet underneath on the flag which is the base of the falls. Could this be a leak or just the condensation. The liner I used is like what a tent ground sheet is made of? I googled it and it said with waterfalls it increases evaporation due to splashing and being able to evaporate. Temperatures have been about 6 Celsius but it has been sunny in the day. Sunny but windy and cold

I would vote leak, the tent ground sheet most likely did not last. or tore a bit

Was the same material used for the entire pond? I did some research and tent ground sheet is the same material as a standard tarp. Nowhere near the material of pond liner, especially under rocks.

The stuff I used had a 40 year guarantee. So I thought it was good stuff. The pond liner is more rubber I'd say or a very thick plastic. It's no big deal if I have to reline the falls now it is all set up. What is the best stuff to use?

This is what I got

quick look at their website and they state it's 0.35mm thick HDPE and a calculation makes that 14mil... so that is not as thick as others have used above.

I will see what they have at local garden centre as I want to get some plants and pots. If its leaking its minimal and should be fine. It's not a massive job to change it just on the falls

Most prefer 45mil. EPDM. second choice would be HDRPE. What you have is HDPE it's missing the "R" which indicates that it's reinforced. HDRPE has visible reinforcement threads embedded in it.

Would this be better? Also now the water is clearing up you can see some silt and sand and dirt on the liner. Is this normal or should I have scrubbed it clean?
That is PVC, not a good choice. I believe we had someone use it to build their pond. Didn't last too long. Your liner keeps the water in your pond so that makes it the most important part of a pond. That's the one think you should never cut corners on. Shop around on line, you will probably find better prices.

go with EPDM or HDRPE and you won't worry. When you re-line, make sure you're creating a concavity all around your waterfall. You want a bowl, something to catch any water that doesn't go where you originally told it to go. Saves a lot headaches later. And your waterfall liner should be overlapping your pond by at least 6" to prevent wicking upwards. If you have extra liner from the pond, I'd make sure it fits up and under the waterfall one.

Good advice from @brokensword - I was a little worried when you said it would be easy to replace the waterfall liner. Best case scenario is always a single liner; next best is a good amount of overlap/underlap. In other words the pond liner should come up as far as possible UNDER the waterfall liner and the waterfall liner should come down as far as possible OVER the pond liner. Water will wick upwards - you want to avoid the potential for waterless between the liners.

Nooooooooooooo do not use pvc procts for liners Hprde or epdm are the two most widely excepted. Then you have concrete fiberglass and polls resins.

The flags I used to create the waterfall overlap the pond liner massively. They are sat on the pond liner. The liner for the waterfall is the tucked underneath the flag which is the foundation of the waterfall. So any water that runs underneath still finds it's way as the falls overhang the pond. The falls is also built up a fair amount on the sides by a good 6 to 8 inch. Since the water has cleared up I cant see any frogs. They were always in the pond before. Will they be in less now due to clear water and circulation? I hope they havent felt forced out

Thank you. I got 3 new plants today. One marginal and two oxygenators. However the second shelf is just over 20cm deep and the pot is 10cm. Is this deep enough? I am also concerned about the size of fish and the limited numbers I can have. How big do fantails as you suggested get?

My old ones, got to around five inches before a heron found a hole in the net. Right now the ones in my hot tub pond are a 3-4 years old and about 4ish inches. They can grow to 6-8 inches, great for a small pond. They also breed a lot slower than gold fish do. Out of my 9 fantails, I got 3 babies last summer.
