Pond Filtration system

I'm running a carbon filter pond filter for my 1000 gallon pond, but the problem is my pond keeps getting a thicker green discoloration, its gotten to the point where i cant see 5 inches down into the pond, the fish dont seem to mind at all, actually they are thriving happily, but i would love to see them at times other than just feeding time. Are there any plans for building an in expensive pond filtration system that could help stop this green stuff from forming, and what would be my best filter media?
also, i heard placing magnets on/in the filter around where the water exits will destabalize the algae cells causing them to die, will this really work?
what other solutions might there be that i can use that will be imediately effective

well... I'm not sure that I know of anything that will be instant... green water is normally a sign of too much in the way of nutrients, so you could do water changes, or somehow cutback on the light, but the former is probably a better solution. There are those who kill excess algae in the pond and aquarium with UV sterilization, but I don't think it'd be cheap...

A UV Sterilizer plumbed inline with your filtration would solve your problem, in so much as remove the free floating algae from the water column. You definitely want to test and make sure your nitrate levels aren't rising though. I found that most ponds aren't getting nearly the volume of water changes that they should have for the well being of the fish. Nitrate is nothing more than fertilizer for plants, so algae blooms are usually a sign of excess nutrients in the water. This being said, I've seen very healthy pond systems with low to moderate nitrate levels have a bloom like that during weather changes, or when its just plain sunny for too many days in a row. Hope that helps,
