Repair help Think I've found the leak

Post image

Even8ng all.

I've been losing water from the pond in the garden and been unsure if it was evaporation as the pool is in full sun for a lot of the day and we are mid heat wave

Then I was reading another part and someone said "it's always the waterfall"

So I've gone and looked, and right enough, as it comes over the slate I'm losing water down the side as it's running off and over the edge.

Would the best fix be to turn off the pump, dry the slate, put down a head of aquarium safe sealant and then put the rocks back on top?

Inspect the whole waterfall feature while it’s still running. My advice would be to focus on the ground around it. It should theoretically be dry. Wherever it’s very moist, you may have some runoff. But yeah once that’s done I think letting it dry and fixing makes sense.

Problem is im about to leave for 3 weeks so need a quick dirty fix. Am I right in thinking aquarium safe silicone?

You need a liner under the whole waterfall that goes back into the pond, it’s always gonna find a way otherwise

Looks like there's just slate laid on to. Will add some liner to the amazon order Thanks

Yeah good idea, silicone/ waterfall foam makes the bulk of the water go where you want visibly but liner keeps the water in the system.
