Im kicking around the idea of trying to build a minnow cage to try and breed fatheads in so when the young hatch they will fall through the netting and out of reach of adults. Is it ok to leave treated delta in a small pond? I though i had heard some treatments on fabrics can be toxic. Also anyone have recomendation on where to buy small qtys of delta netting? I tried one place by never could get a response to their email order form. Ive been using netting from joeanns for my minnow net but it just doesnt hold up.
