Backyard Aquaponics
A place to discuss aquaponics

I tried 90mm all the way (worked OK) then at the base of the T (to tank bottom) I tried 50mm and it worked better. So then I stepted the 50 down to 32mm with an angled cut on the bottom pipe and works the best of all. Mind you I still have 90 T piece and out the side exit of the tank all the way to separation filter..

The tank holds 20 large Barra (big poopers) and I can tell you that when I pump up a big head in the tank, say 100mm above the T piece, with an extension on top of T Piece (6000 L/m into IBC) the smaller pipe creates the best suction and velocity to pick up the crap. Can easily remove and put the 90 back in, but why

bit of a update

well nearly getting there

i think there's something wrong with my water? talk about a red tide



well thats what happens when you wash scoria in it, looking like rain tomorrow so ill drain and refill it if it does , the grass seems to love the red dust sludge, its doing very well



what can i say drilling holes got tedious so i just die grinded out the sides of my tube and fixed gutter guard mesh to the holes works quite well actually.



a shot showing the layout going to move fish tank and filter a bit try make it more compact




first one filled with washed scoria talk about time consuming

yeah scoria is a b1tch to clean
is that filter mesh staino? if not it could cause you problems . .

nah its just plastic

well i can say its operational as of today will run 2 left beds until i get more scoria to fill the other 2

oh btw it drains in 3.5 mins is that ok takes a while to fill maybe 15mins or so
ill time it properly tomorrow

hi i recently transplanted some lettuce from planter box to gb and today they look wilted do they usually bounce back


what can i do to try and remove the dust in my water from scoria atm i have some filter wool on outlet

Nice one, did you sort out the washing of scoria? Clean water now?

not yet got some wool on outlets might try the egg thing or at worst wait for the rain and water change

well the egg trick did work a bit , then stunk for a week ok now
still wanting to do a water change,waiting on the rain

bit of a update

got some beetroot, brocolli ,cabbage seeds growing on the left side
and lettuce on the right parsley in middle



strawberrys on the left and rosemary and capsicum in dome trying to survive the winter some dill in pots as well



both of these are 1/4 full of scoria planning on topping with hydroton still a lil murky but slowly getting better



long range shot

system is for sale, check the classifieds

Expansion? Moving? Or just didn't work out?
