The big girl "Sluice Almighty"is 6m at the moment,
Interestly the last section of expanded mesh over moss had mostly very flat and very thin flakes
Great surface area verses weight hard to catch!!
Not much of the really small specks were down there
They were in the top box and the first 1200 of UR Hog Mat
Very interesting experiment can't wait to get back up there
