so me and a friend been checking out the uc systems and we want a 12 site system and are going to try the diy approach. so im wondering if five gallon buckets will be good enough and using the fives would it be ok to use 1 1/4 pipe instead of the two inch that current culture uses with the 8 gallon rectangle moduals. we are just going to build a four site system to see if diy is going to work with us. and will be using a danner drive 250 gph as well. thanks any who respond.
