We had a horrible storm last night and our drainage ditch overflowed causing tons of dirt to go into pond. Our pond was crystal clear coming out of winter and now it is completely brown can only see probably 6 inches down so far today. Was hoping the filters would catch back up but even with them being cleaned there is still atleast 1/2 inch of dirt/gunk all along the rocks that have settled. I was thinking a vacuum would be the next thing to do but have no idea if that's even worth it or if we should do a drain and clean and I really want to avoid that this year. Had to last year because our fish came out of winter really really sick. I had to put them in stock tanks and treat them, all survived! The year before we had to as well because we had to many fish. Our pond is 4,500 gallons. It has a liner with rocks covering the liner throughout. I'm drawing a blank on my filter right now but it is a waterfall filter and we have a skimmer. Any help or suggestions is greatly appreciated I do not want to loose my fish
