This 50mm Bottom Drain with built in air diffuser is made for concrete or gunite tanks or Koi ponds.

It has dual functionality, to drain solids from the bottom of the tank and to suuply dissolved oxygen via the diffuser disc mounted on top


NOTE: The air inlet is 50mm by default.. Can be customized for smaller inlet, but adds a few days to lead time
