Here is the plastic media I use:

You can use up to four cubic feet in a 55 gallon (208.2 liters) drum. 7.49 gal (28.4 liters equals one cubic foot.)

You may have to settle on kaldness K1 in your region as it's used extensively in Europe. Unfortunately over twice as much in prices as the media above and not as much surface area.

OTH you may want try something different and if you fish load is small you might be able to pull it off.

Yes still use the deer fence netting and a siphon. KISS principal and cheaper too.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
