I have sponge, plastic mesh balls, hefty coarse filter media (meant for a chimney/stove), rock, and tons of polyfill. All in random layers. Pain the behind to clean but I rinse everything 1-2x a month (except for winter- filter is off). I would be hesitant to use barley straw in a filter simply because it degrades quickly. I know some people put bales of the stuff in a pond for clarity and algae control. I have used barley extract in the past but I honestly dont think it did anything special and it was pretty pricey.
Ok thanks again
I know last summer I had a ton of algae but with more water changes and also adding floss I was able to keep it under control. So maybe I'll skip the barley and just do a simple filter with normal things and go from there. What's plastic mesh balls? I have the normal bio balls but mesh I've never heard of.
