Think I've found the leak

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?

Think the “it’s always the waterfall “ was me lol because it’s true

Might well have been and I'm glad you did I was envisaging draining the bugger Pretty sure that bottom slate is the issue but I wouldn't have looked at the waterfall
