Hi all need some advice I have 2 ponds one to go into the other for airation.
Had a waterfall and kept leaking finally found water soaked and believe it was from the blade being put in incorrect.been told can't have a blade by one person but don't see why can anyone help and make a suggestion I've attached pictures and happy to change the top pond so I can accommodate a fall into the big pond. I have spent money on the oase filter and pump so thought if gravity fed blade? Excuse the mess just protecting the koi from the heron and trying to sort this mess!

You are planning on lining the top box I'm guessing? The blade appears to be too short and the water will run back along the bottom. Also make sure the liner for the top pond goes under the blade and is sealed. Wouldn't be a bad idea to have the liner form the top pond extend down below blade. I have a similar setup and had to extend my spillway out further.

so this 'blade' is the weir? I can't see why you can't have one either. Is it leaking along a seam? Do you have a liner in the upper pond that you can just send any overage under your weir and over the wood cutout? I'd seal there with silicone or PL GOOP. Should stop any leaking.

(ditto what mrsclem just said!)

You can also put some sort of drip edge so the water can't back itself up. A bead of silicone along the bottom front edge of the blade would work.

Thank you...yes I had to remove the liner as the "pond fitter" fitted a new one over the top of the old liner ..problem being that also filled with water I took it all out on Saturday to try and dry the wood get a new liner and start again.
I've been looking at gravity blades similar to the one attached. It actually was lovely when it did work

My hubby made me a stainless steel weir but it is welded to my stainless steel waterfall container. You can make it out of the plastic also and it should work fine as long as you have it situated correctly so it can't leak and if it does it will just leak back into the pond below and not damage your wood.
