Flood table used as nft

I was reading a thread a little bit ago and someone posted a pic of their own setup. It used a 4x4 flood table. But instead of Rockwool or any medium he had a table top with holes drilled in it. He used neoprene collars and aero cloned into the tops. He ran the ebb and flow sort of like a nft setup. Just wanted to see if I could find the person and or thread again?

@ANC uses some sort of nft setup on a table. track him down...
