It`s just my opinion but I think you are making it much more complicated than necessary. I have two tanks with manifolds and the fish and I love them. One (50) has Reticulated Loaches which have spawned repeatedly, Panda Garra and some rosey barbs. The other (125 gal.) has five barilius canarensis, five sumo loaches, six clown barbs and two red tail tinfoil barbs, who all love to play in the current. Simple construction, no glue, two good powerheads, a couple pond pre filters and it`s up and running.
