i got my new tank set up, but the water just runs out of the return line from the pump whereas before it shot out with pretty good force. i am using an iwaki wmd-30rlt and have 4 return outlets. i had always used hard plumbing before, but the dang bulkheads on these all-glass tanks have nipples on them for soft plumbing. so now i have hard plumbing going to the pump from the sump and have hard plumbing coming out of the pump with a plastic nipple to convert it to vinyl tubing. this goes into a t that splits and goes to each end of the tank to the bulkhead nipples to go up the return pipe which each split into 2 returns for a total of four. i cannot get any decent pressure to come out of these regardless of what plumbing config. i use. plumbing is not really my area of expertise, so any advice would be appreciated. i am using 3/4" inner diameter tubing and pvc. should i use wider plumbing? do i need a bigger pump? any suggestions on how i can use all hard plumbing and get rid of this vinyl stuff?
