those ponds you see in the woods are not "standing" water. They filter naturally...water comes out of the ground to form the pond and filtration is happening. Natural ponds aren't stagnant, nor are they faced with concrete or a liner. We are trying to "mimic" a real pond, but in order to do that successfully, you have to filter it as it is a body of captured water, AND you have to do partial water changes.
Plants help a bit, but not enough to sustain life. If you just want to do no filtration, you can throw some plants in; and then just expect that your water will always be pea green and soupy. You will get mosquitos, so I would use those mosquito dunks you find at home depot. I would not put any fish in something like this. Not fair to the poor fish, who was not destined to live in a non-filtered concrete tank of unkept water.
Chemicals like algae remover will not be useful without water changes. You're wasting your money. Your water is green because it is not filtered properly and maintained to proper levels.
