tomorrow is manifold day

[graphixx]

allright tomorrow I am redoing the manifold on my tank (got a home depot gift card for xmas) i am gonna do 1inch pvc.
the existing manifold on the tank right now is a mickey mouse rig. right now its half inch pvc and there are only 4 ports (one in each corner).
so what I am gonna do is upgrade to 1inch pvc and I am gonna do a total of 10 ports 5 in the front and 5 in the back they will come down and then i will attach 45 degree elbows on them and angle them in various directions.
Here is the pikel I am in. I CANNOT do an external pump (well I can but I really,really,really,really do not want to drill the side wall in my sump) I have been searching for a good submersible pump and the biggest I could find at a good price is a MAG its rated 3600 gph. Do you guys think this will be enough to get some good movement through the tank???
I am also gonna drop 2 small powerheads in the tank and run them all the way to the bottom and hide them in the rocks to get movement on the bottom of the tank.
I need some input on this. I am gonna order the pump tomorrow hopefully.
what are your thoughts on this??? thanks guys I appreciate it

I think that if you run 1 inch pipe then downsize the angels to like 3/4 it would help build pressure that may create more flow. You may also keep in mind that later down the road if you adapted loc-line to the ends with flared tips it would do the same thing and you could adjust them a little better.

You can always do another closed loop in the future if neccessary, so for now, why not?

I am gonna do a flared tip on the end of the pvc (easy to do just heat and crimp) so I have that going for me. I just need to get all these damm powerheads out of the tank. I am almost ready to start on the canopy and need to this manifold done

[jojo22]

that pump is only going to turn the tank over 9 times an hour. Don't know if you did the math but that is not very much. What powerheads are you useing and is the 3600 GPH after head loss??

[graphixx]

THAT IS THE IDEA OF THE MANIFOLD. is to get rid of the powerheads. I dont want them in the tank.

[graphixx]

your head loss should be approx 8% or right in there

[jojo22]

You said that you where going to use some power heads in the bottom of the tank hiden in the rockwork in your original post. That would add to the total turnover correct??

I am also gonna drop 2 small powerheads in the tank and run them all the way to the bottom and hide them in the rocks to get movement on the bottom of the tank.

ooooohhhh yeah. sorry buddy. yeah I want to do that to make sure I dont get any detrius settle on the bottom :D

[graphixx]

something I forgot to mention is that I also have my plumbed returns (the ones that comes installed in the tank) and I am upgrading that pump to an 1100 gph pump so that will help

[jojo22]

well I guess without all the specifics of how many GPH all these pumps are combined after head loss it would be next to impossible to answer your question about whether or not we think that the new pump would be able to provide enough flow.

[hummer]

what about 2 mag pumps one mag gets 5 outlets this will get your flow up there just a thougt :):) hay buddy just started glueing sump i have some pics will post them soon on my thread in dyi ,,,55 from the start

[pass1over]

i was thinking about putting some hidden powerheads on the bottom, but how do you stop their inlets from getting clogged? just have to take the rocks off and clean once in awhile?

[carpenterwrasse]

It might sound goofy but don't drill the tank just 90 it i know there will be some loss in presure but it would eliminate the drilling of the tank
