I have 3.3 acre pond in Northern Virginia. I have a vertex aeration systym, 20 grass carp and am now going to try some barley straw. I just got 30 25 lb bales to put in my pond. Should I put them around the aerators? In bales? I have read that you should make tubes out of tree netting (where can I get that)? I would also love to add Tilapia as Filamentous Algae is my #1 issue but you can't buy them in Virginia (I don't think). Any ideas ... thanks in advance
