Spent a bit of time today getting this project underway.
Had some netting from one of my recycled trampolines, stiched it up into a sack.
Filled this sack with seaweed which I gathered from the beach, need alot more. Popped it into a 200 ltr drum which I picked up for a fiver.
Filled it up with water.
Going to get some more barrels and a much more seaweed, thats the plan anyway.
