Hey all - I'm new to the forum, and relatively new to ponds in general.

We have a pond in our front yard that is in constant motion. Our domestic water comes from a spring that feeds a collection tank, and once the collection tank is full the overflow runs down the hill and fills our pond. Once the pond reaches a certain level, it flows out of an overflow drain and hits the stream beside our home and keeps moving down the line.

We're having a tough time keeping the algae out of the pond. We've tried various algae inhibitors, but they're short-lived due to the constant movement of the water... Meaning I think that they are mostly washed downstream with the pond overflow - if that makes any sense.

Is there a better way to deal with the algae?

Currently, I just let the point run for a week or two, then drain it completely. I lightly scrub the pond walls, then refill. It's about 10 days to two weeks before it gets just crazy nasty, then I do it all over again.

Should I be doing something differently? Something more effective?

I'd love to get some advice on how to better manage this, as it's a bit of a hassle to drain/scrub/refill every ten days or so.

Maybe there's not a better way - but I wanted to inquire nonetheless.

We're in Western Colorado, where it's relatively hot and dry most of the summer.

I'll try and post a current photo of my setup. You'll see the inlet and overview drain...
