    If u are lookn at the falls.. look to your left on the last falls it looks like there is water going out.. it might be just the angle.. also like tad said check ur fittings . If you have a filter tank check the bulkheads where ur hose goes in.. do u have a skimmer? Check the bolts you may not have a good seal..

    I suggest you try again to see the video - it's not a masterpiece (lol?) but it does give you some idea of what I have built.

    I am not sure if the questions around sealant have anything to do with the water loss. I used a sealant to stop - or at least reduce - the water going down the back, instead of the front of each 'face' (is that the word?). As far as I understand it, this was a 'horizontal' application of the sealant.

    Because of the weather, I have not had it running all the time, and I probably will only be able to check this out in the spring.

    Tried to view the video again, but gave up after waiting 5 minutes for it to load.

    The use of the sealant should not have anything to do with the water loss. I questioned its use because 'Black Foam' is used pretty much universally by Water Feature contractors because it expands. Lap Sealant, which is what you used, is normally used in seaming applications.

    Can you post some photos of the project?

    I was not (and still am not) that well informed about the differences in sealants. I spent time doing research as best I could, and I selected Firestone AP Sealant because of the color - I did not want black.

    I have uploaded a frame from the video....
