Okay... 3.5" from the back on the floor/bottom are three holes that are spaced somewhat like: o-------o--O and they are 1" and the last is 1.25". Then in the center of the floor/bottom, there's three more 1" holes spaced 18" apart like.......o...........o.........o........
So does that give a better idea? I'd like to run more than one inlet, I was thinking about having a rail of pvc
like l______l______l only flipped over with holes drilled in it for water flow inside the rockscaping (I have a LOT of rock, over 180lbs and planning to add another 50lbs min) that ran off the three central holes, and taking the big hole at the back and running a pvc
pipe on that for a durso standpipe style overflow minus the overflow box, with the two holes beside it plumbed with pvc
and that funny triangular moving pipe stuff (loc-something, saw it on another related post here) for surface agitation. My only concern is that one drain/standpipe wouldn't be enough for the amount of water I need to keep circulating through here. Should I drill another big O next to the o-------o--O so it's like O--o-------o--O? Then I could have two standpipe/returns. I was thinking continuous flow on the l______l______l since it's in the rockwork, but I could be convinced otherwise. I also thought that little scwd deal as pretty cool idea for maybe the center post of the rail with the outer parts going back down to the sump? Sump wise, my main filtration is biological and one monster skimmer, I was going to piece the sump into a intake side where my monster skimmer runs, through a couple bubble baffles, then flow into two fuges (one mangrove/mud and one sand/macro) and from there flow through another baffle to the return pump side. I was planning on two dolphin amp master pumps, one for the skimmer (skimmer's rated Ungodly) and the other for the return(s). Could I run one external pump for return, with the return y'ing to the two surface agitation pipes and the scwd run center rail? Or should I run it like, instead of a center rail, 3 pipes with scwds in the center and t pipes drilled but capped? As in:___l___ ___l___ ___l___ or is all this too elaborate and I'm just making things harder than they need to be? I've really learned the importance of random waterflow over the years, so I dont mind a fortune in scwd's if it's necessary.
