Recommended Pump for EX-1

After reading a few posts on the DAS skimmers, I may have over bought on my skimmer pump (Quiet One 3000). What pump is recommended for the EX-1?

I was thinking that maybe I could still use the Quite One 3000, and drive the EX-1 and other filtration equipment like a couple of media reactors and a UV, but not sure how I'd plumb everything.

I don't have enough room on the intake of my fuge to place the Quiet One 3000 in, so I was going to run it externally (drilling a hole on the side of the fuge and mounting the pump there). For you folks that are so inclined, how would you diagram this out, where I can use one pump and drive up to 4 other pieces of equiment (EX-1, 2x Media Reactor, and a UV)?

TIA,
Jerry

I direct feed my EX-1 from my overflow; my return pump is pushing ~500gph and my fuge gets the lion's share - I don't think there's more than 150-180gph going through my skimmer.
 
So to understand correctly, you tee off your drain to send some towards your skimmer?

I'd still like to have some way to feed other equipment, as mentioned. Wondering if I just come off the pump and have T's and ball valves for 4 devices and the regulate the flow using the ball valves. Does this sound like something that would work?

The plumbing arrangement would look something like a 4 pronged fork, with each of the 4 prongs having a ball valve in it. The tip of each prong will have the proper fitting to run flexible hose to. The return for each of the 4 devices will drain back independently into the intake section of the fuge.

Sounds like a mess I know.....
 
the valves thing could work, and you wouldnt necesarily need to do a 4 prong split then feed each indicidually, you could feed them in line slowly decresing flow as you go down the line using ball valves. i am going to do something similar on my tank. heres a diagram how i plan to do it, will be giving in a try in the coming weeks after my stand is done.
 
Thanks Wes! Seems to be pretty straight forward.... I like it. Just to clarify, the sump/fuge block you show is the intake section of the fuge. So you will just bypass any over flow from the pump back into the intake section so to not put too much back pressure on the pump?

Thanks again Wes!

yes, it just loops in one section...pulls from one and returns to same...make sense?
 
also, please note, this is a design, work in progress, idea even, sorry, i meant to mention that before...my dad does yard sprinkler plumbing stuff, and just a short convo with him a while back over the phone he said it should work out well, but i have not tested...let me know if you use ir
 
Will do Wes, series feeding everything should work, and had considered that first. But, my earlier description of parallel feeding the equipment just kind of popped into my head as I was typing the post.

I like your idea as it will help the pump last longer and keep it cool.
 
Are you sure that you'll have enough room for the manifold?

I'm a bit of a nut but I would probably put a ball valve and a true union on each component so that individual items can be removed for maintenance without shutting down the whole system.
 
Yeah, thought about just going up, across, and then down on the intake end of the fuge. Hopefully it will be enough.... We'll see....
 
There is one more thing to consider with any 'log'/manifold type system and that is that pressure/flow adjustments of *any* leg of the manifold will cause a ripple effect on the pressure/flow on the other legs even with ball valves,etc. These effects are sometimes inconsequential depending on the available pressure and flow, but are sometimes pretty dramatic too. For instance, shutting off the media reactors to replace the the media *may* cause an overflow on the skimmer if more water is allowed to enter it... so during reactor maintenance you might need to shut off the skimmer too or it might slowly (or faster) fill up and overflow the neck. This will be especially true if the water from each of the *devices* on the manifold is returned to the sump rather than re-introduced down stream a bit in the same manifold (which opens a whole other set of considerations :? ). I currently use manifold setups on both of our largest tanks, but it does occassionally catch me by surprise when I forget and shut off one valve without compensating somewhere else (and then resetting again later). On our largest tank we "power" almost all "devices" (including a DAS EX-2 skimmer) from one large pressure rated Iwaki pump and it works OK. There are ways around this too, but it would get seriously expensive to try to compensate. Just be sure you are not feeding something that is *very* sensitive to water flow/pressure (like a calc reactor) without considering it.
