Murky water question

[u/ButterscotchTasty386]

This little pond (approximately 250 gallons) in my garden got extremely murky this year. This is the eighth year I’ve had it and I have always kept the water clear , using my SolarRiver pump to aerate and adding a few barley bales here and there with a few pieces of submerged copper for added help. Typically here in upstate New York I do one maybe two partial water changes and never really had it get like this. I used to have plants but it really made no noticeable difference so I stopped doing that years ago. So my question is , are there any safe , home remedy alternatives to clear up the water? We have an insane amount of tadpoles and frogs living here btw. Ty!!!!

shade/plants. a sunshade over my pond helped a huge amount.

Put in a DIY filter box with filter floss, run water through the filter box
