I've had a few questions and pm's recently about this set up, so thought I would take a few snaps while I was doing a res change.
some people don't give a shit and some already know but its just a big res tank and a lid with holes that the pots sit on, theres a submerged pump that recirculates the res water.
heres the 50 litre res tank
and the lid
stick an airstone or two in
ph the res
and stick the pump in, pots on and drippers stuck in
