Top picture of the bed, this bed will be updated soon, we will be creating a bed the size of the table top, 800x1800xheight of the tub here as this size is pretty good. will be making it using 2x4s and thin plywood for the sides, and pool liner (cut to size).. (just like the find pond below).

temporary setup holding the pipe in place... but just a normal kitchen scrubber which has holes, catches all the solid waste, easy way to change the filter and clean it without to much disruption.

bottom of the big bed, we put this on, reasons... 1. kicks in the siphon much faster, and stops it faster.. 2. also closer to the water level so really quiet when siphoning out water back into the pond, also still creates bubbles.

side on close up of the u-siphon, got the idea from youtube, works mint as, the end bit (looks like it shouldnt be there, isnt meant to be, its meant to just be 1inch pipe that nearly goes to the same level as the taped pipe.

bought a 54L tub, changed all the hydroton (clay balls) into the bigger container and using a u-siphon, the small pipe is only to see the water level. took out the gravel guard and left it without it, so far no balls have been sucked up, but am planning on putting a wiremesh around the inlet hole.

took bed apart to upgrade it, changed from a bell siphon as it never really worked, this u siphon works great and needs less space, can change around to get the right height as well.

Previous attempt to get water to the bed with small pumps, 1 pump to the bucket then another pump to the grow bed. Replaced with decent water pump
