Filter is made of plastic collander, window screen, polyester fiber fill. Has a styrofoam collar for flotation. Solids are lifted through 3/4" PVC with a 3/4" to 1/2" Tee at bottom to allow airstone insertion from the side. As air rises in tube it creates bubbles that make water in tube more buoyant and rises sucking in water from below together with the solid wastes. Notice the green vegetation residue on the screening material.

Shallow Raft Growbed of Landscape timber frame with pond liner at second level (on ground)
Bridge Syphon from growbed to sump extending from growbed water level down to lower than growbed level. Sump partially burried in ground and contains a max flo pump. Water is pumped up to IBC and allowed to overflow into growbed which syphons back into sump.
