Flow questions

[Andrew_bram]

So here is the deal I am an absolute flow junky. What kid of flow would y all put into 36x36 150g cube. I hear flow in a cube is tricky trying to wrap my head around this one. Who has used maxspect gyre either new or old. Who has used the new mp40. Who has cubes.

What would be so different in a cube as compared to anything else? Would thibk the principles would be the same. 10x flow rate to the sump and 40-80x flow rate via power heads in the tank depending on what you want to keep. Only difference I see is maybe you need more power heads to make sure no dead spots.

Dead spots is where I would worry how to maintain nice look no clutter.

I have the Maxspect gyre XF150 in my 150 gal. (48x30x24) and I really like it a lot. I found the reverse pattern to be worthless, so I just keep it at a steady state 24x7. I tried the pulse function for like a day until my wife sat down at the couch and asked what was making that pulsing sound. I'd be interested to see what a second gyre would do placed vertically on opposite corner of current horizontal one, but not enough to pony up the dough to really test it!

I have the gyre 150 (x2). Their newest version is much better than the first IMO - still trying to get them to give me a free swap. If you were to go that route, I would put one in a corner vertically and let it wrap around the tank. Better yet, put two and alternate them - mine are each on for 5 mins on opposite schedules.

Is yours new or old gen

I was thinking about running 2 side by side. Horizontal on back.

I am not sure that Maxspect actually Gen'd these, but I probably have one of each. The first "gen" had a different foot pad layout that was too close to the body and with less real estate - it would not get as much grip on my 3/4" acrylic. Also, I have been noticing that the first gen tends to be finicky about freezing up if the cages are not perfectly aligned.

Cubes can be easier because you can do front/back and diagonal that are very hard in a rectangle. I would do diagonal and front/back with 4 pumps. I would put a wavebox in any tank, cube too, to keep the debris suspended as much as possible until it blow away.

I think this would be great, my concern would be if your rock work would disrupt the flow....it may never get beyond the rock and would go back to the surface? There is a diagram of this layout in the gyre manual I believe.

I am trying to keep sides as free as possible

Here's the picture I was thinking of:

 

[Andrew_bram]

Thanks for the flow diagram. If it was disrupted I am sure my spare mp40 would help make some turbulence

I'd use two mp40's and either an L1 or M1 return pump. You aren't putting too much flow through the sump until you're getting micro bubbles in the display. In my 40 gallon frag flat I'm using an M1 for a return with 1 MP 40 and really wish I had another MP40 to add to it. My 270 has two L1's coupled with two mp60's and I think that's about right for a 6' tank

Do you keep your Mp40 dialed back on the 40?

 

[aquarius]

I've been curious about the max spect but as already stated the reverse flow can be lackluster and I really like the controllability of the eco tech pumps. My frag flat has two 1" drains and they just barely handle the M1 at 100% and 2.5' head height, so if your in the planning stages and go with one of those I'd recommend at least 3 1" drains.

 

[aquarius]

These are my mp40 settings

 

[Andrew_bram]

Return flow is not where I am concerned this will be plumbed it basement. I am trying to figure out my in tank flow without sacrifice of clean look. This will be a downgrade in tank size for me.

 

[aquarius]

Then why isn't return flow a concern? If you can get 3000gph out of your return that's one less powerhead you need providing a cleaner look imho

 

[Andrew_bram]

I prefer slower turn over rate in sump personally to allow skimmer time to remove doc and provide better environment for macro algae to do its job. I have never counted my return pump as flow. On my 220 I run 2 wp40 a wp25 and an mp 40. I also have constraints on the cube as there is only one drain and one return
