We have our homemade weir in our upper pond which is a pre-formed pond that falls to a sream to the main pond. Due to where the weir is the laundry basket did not work, We went to W*lmart and purchased a square file holder that has a bunch of large round holes in it. To ensure that the stuffing wouldn't float out through the top hubby used some more of his crab trap (the legftover pieces holding the foam media in the weir) to make a removeable lid whic he held down with cable ties. Right now it is not the prettiest site, as the hose had been cut to only reach where we had the weir originally. We put some pavers in the bottom of the pond to raise up the file folder crate so that the top was aove water and we set the weir on top of it so that the water spills directly into the filter.
I will try and snap a picture so you can see what we have done. THe green water is really bad this year. My plants barely have any leaves yet and our pond is in full sun the better part of the day.
