So once a week, one side gets scraped clean? And grows back in a week? Drip thru sounds great for fry! Thanks!It gets removed once a week, typically alternating sides on a 2 sided screen.
I have a experiential "Drip Thru" and "fluidized ping pong ball" That will be self cleaning, if possible.
The drip thru, has been feeding some african cichlid fry .Automatically.
