I have a couple underground springs that surface in my yard that I dug out into and ornamental running "pond" that exits into a drainage system
It looks nice and it stopped the water from backing up into the rest of my yard, but its not an actual pond, the water runs straight through left and top to right in the attached picture.
Only issue I have is that algae keeps building up in the water, every few days I go out and skim it clean.
anything I can do to prevent this? i would prefer not to use chemicals and I think they would just wash through into the drainage pipe anyway.
