Prevent Algae in waterfall

[420benz]

Is there a clear paint to prevent Algae from sticking on the flat surface on a waterfall?

algae on rocks is perfectly natural, and you dont really want to completly rid it. If you need to get rid of the algae, you could scrub the rocks on occasion, but I would reccomend leaving it be, although for a more deataild answer we would need more info about your setup.

Its not the rocks its a 4x4 flat flagstone surface the water from the waterfall runs on then drops into the pond.

No, I don’t believe there is anything you can paint on that will prevent algae. Algae is going to grow on just about any surface.

Is there a particular reason you don’t want algae in this particular spot?Please post a picture of your problem area and maybe we can help come up with solutions.

Maybe you have a good reason for getting rid of the growth on the rocks.
Personally I like moss or algae growing on the rocks. Seems like a natural thing and it looks nice. I strive for the natural look in and around my pond.
But, again, you might have a good reason.

There's nothing that will prevent it permanently, but you could use hydrogen peroxide or sodium per carbonate from time to time to clear it. Being that it's a flat surface, it would be very easy to just shut off the waterfall, dose it with either product, let it sit for 20 minutes or so and turn it back on.

Alternatively, you could just shut the waterfall down on a hot day and let the sun bake it. But if the waterfall is connected to your filter, that's not a good solution.

This is after I pressure washed it today.It was black before.

I get a build up of what I call 'carpet algae' (because it's sort of a heavy coating, like... carpet! lol) on my flat rock sections of the waterfall/stream area. If it gets so thick it's diverting the water flow, or it's aesthetically bothering me & I don't have any more pressing chores to complete, I simply rub it off & remove it by hand. I'm not going for 'brand new clean' though, just enough to see the rocks again.

I wonder if plexy glass will work?

 

[Mmathis]

Algae will grow on plexiglass, just like it does on the inside of an aquarium.

Bummer

That's probably more biofilm than algae, but in either case if you can power wash it off then that's probably your best option.
