hi I'm in the process of getting the parts I have some nice 18lt pots 40mm pipes T's ect
13mm tubing for waterfall in each pot. my only problem is what can i use for the brain

the pots are 18lt but be filled to 12lt so they hitting the bottom of the net pots all pots are connected
with 40mm pipes i know gravity plays a part of keeping things level. the res im thinking of getting is 35lt so
does that mean the res will hold 12lt or does the res hold water to the same height ? bit confused on that one

and im thinking about adding a popup tank, i know that can be any size but where can i get the parts locally without going to a grow shop that will work with the 13mm tubing ?

please bare in mean im in da uk


thanks
billy
