Straw for algae control in stock tanks
I use straw to prevent and control algae growth in my stock tanks. The recommended straw to use is from barley. I have oat straw available so that's what I use instead of barley. I recently dumped a water tank that was green with algae. After rinsing it out and a quick spray from the hose, I tossed in a handful of oat straw. It floated on the top at first, after a few days it sinks a bit. Slowly it will break down and eventually the algae will refuse to grow. A safe and natural way to save time and keep the stock tank clean without scrubbing it. Has anyone else tried this?
