Vortech MP40's on the Back wall of a Deep Dimension tank

[110galreef]

How wide is the flow?

My tank is 66x 36 x 24. I currently have a CLS for flow, Dart Gold thru OM 4 way. Overall very nice flow, but the tank & SPS need more.

I can swap out the DART Gold For a Hammeheard, add 2 more returns and this will increase the flow about 60% plus two more random out puts. ~ $300 for the pump swap & extra plumbing. About and extra 100w of energy.

Or, run 2 MP'40 along the back wall. Attached is a recent pic of the rock work. Still lots of growing out to go. I don't want to put anything on the sides as I want the tank clutter free and as clean as possible. I was thinking putting the MP40's alnong the back wall just outside & below the external overflow box(can be seen in the pic pretty clear. About $800 for the 2 MP 40's, only and extra ~30w avg. No extra plumbing headaches

Will the flow be wide enuf to not just blast the back of the rock & corals, give great undertow & get thing mixing up??

The left & Right Main Islands the tops are atleast 8" away from the back at the edge of the rock and the center of the island is about 16"from back).

i think they would have to be turned down too much in order to get them to work ok from the back, id just add them to the sides. the footprint they have in minimal and you will see a great benefit to having them there.

Here is a photo taken from the left front corner on an angle....was originally a 3D pic so hopefully still looks good and helps show the rock spacing.

Yeah I know the best bet is sides, just not happening. I'd rather just up the CLS, keep everything hidden behind rock get the flow. Unless on the sides near the back wall, but probably defeats the benfit as well.

The MP40 on the back wont be shooting righ into rock as they will pretty much should have free blast to the front. Until the SPS way over grow! :dance: but i can trim SPS if need be down the road.

[pnavarro170]

well the flow is pretty wide. but might be better if your set on it to do just 1 mp60 it has amazing wide flow.

[110galreef]

Hmmmm......Not sure how one mp60 would make a wider flow than 2 MP40's. Plus id imagine if anything the MP 60 on the back would have to be dialed down quite a bit to not stir up sand as it hits the front pane.....

I think the 2 MP'40's would work and be more beneficial in flow & undertow than adding more CLS flow. But don't want to spend $800 & be WRONG! :-O

[pnavarro170]

its only $700. haha. and yeah its hard to explain, mp60 dialed down to 45% would do just as much as 2 mp40's at 80%, my tank is only 4ft long and the 60 at 40% moves the sand bed on the other side. mp40 at 100% doesnt do this. the flow is 3-4 times wider in the 60 though i believe also.

[110galreef]

Ok, so you think 1 MP 60 is better than 2 MP40.....if so I'd love to have less stuff in there.

So then the 1 MP60 on the back or just pick a side of the tank near the back and place it??

[undertai]

1 mp60 would do; or 2 mp40w and have them put in sync.

I've been spinning wheels on the flow thing for quite some time now. Im also in the process of choosing direction to take. In order of importance: Energy efficiency, looks, price.

My dilema with vortech is that they seem loud. Take up a larger footprint outside of the tank (I have something almost flush to one side of the tank). Expensive.

When reading up on the Vortech's. I believe that i read that they are not that efficient on slower setting. Meaning that they have an idea operating range. I'll be damn if i can find that writeup now. Someone please correct me if im wrong on this one. I hate to spread misimformation...

In my situation, it seemed that it would almost make more sense to run 2 mp10's at higher speeds, rather than 2 mp40's way dialed down on a 90g. I would have to run mine on the back wall as well. Wouldnt 3000+ extra gph do the trick for you?

[pnavarro170]

one 60 on one side would be better than 2 mp40s i think. wide flow is the main reason i like it.

[110galreef]

Hmmm.....They videos on youtube of the 60's do seem sweet. Any vids on here you know of?

[pnavarro170]

none extra that i know of. plus even if you didnt like it anyone will buy the 60 from you. they dont lose value that much. but it seems like it would fit the bill for what your asking.

Mounting on the back panes will also reduce any noise produced by the pmps, awsome fringe bene!

3 on the back and 1 on the side....will eventually move 4 to back and a 60 down the side.

the ends of the 175 are narrow too...all are at 100% lagoon from 0500 to 2200 and on 100% RC during the night.

Very nice. I have a 48x30 tank in the works and I plan on running the mp40s on the back wall. It may not be the best flow setup but my guess is that it will still be plenty good. If it doesn't work out I'll move the pumps to the sides.

I do understand keeping them in the back. I think that even with a small footprint, I still think mounting on the side is distracting vs "clean" look. I would still go with 2 mp40 placed strategically so its not blocked by rock.

Very nice....do you happen to have a vid?
Thanks for the input

110galreef, noise isnt a major concern for you is it? i thought i read in your tag line that your tank is an in-wall so i dont think noise is a big issue
anyways good luck with the decision!
corey

[110galreef]

Yeah noise really isn't a big concern. Between, the dehumidifier, furnace, skimmer, CLS pump....I don't think I will hear the Vortech's.

I am really looking for the cleanest look. Hence the CLS start, but need more.

how are u liking the Vortech 40's?
