Using Concrete To Fix A Broken Waterfall

My girlfriend has a pond with 2 commet goldfish in it that has a waterfall that leaks alot. Like enough water that they have to fill it up daily. So I was wondering if I could tear out the old broken concrete that leaks and just build a whole new waterfall. Or would the new concrete chemicals kill the fish.

fresh concrete might leach chemicals. its recommended to let it dry and cure, then soak for a few weeks and change all the old water.

if its not a big crack, maybe use aquarium silicone to patch up the leak.

I could try the silicone I haven't really seen the whole crack because there is water flowing over it and some rocks stuck in thr concrete. The previous owner made it and it wasn't the best design.

I'll take a pic later today when I go over there.
