WIP - 40 Breeder

[dsmhero]

The idea in this is a penisula build is to have almost everything hidden, which is the reason why I want the powerhead on the overflow side. I am getting hooked on SPS, which I didn't think I would, so this tank will mostly be SPS with a few choice LPS.

AH HA................................lol, SPS can be habit forming and can induce major headaches and spurts of alcohol abuse, be careful. I still think that the MP40 is overkill, but I may be wrong. I wish we could get someone else to chime in here, but that seems to be like waking the dead. I think I was using Korallia 2and 3 in my 40, but then again, I did not have much of a rock structure in there.

I think I know what you are looking for with the MP pumps, and that is the versatility they have as far as flow, am I close?

 

[dsmhero]

LOL, I have you to help me with the sudden headaches of SPS!

You are correct sir. I have heard great things about them, mainly the undertow and wide flow they create compared to other pumps. The controller is a major plus too, get some nice random flow going! I do agree, I think the MP40 will still be overkill, here are a few stats.

MP10
Flow: 200-1575gph
Watts: 8-18

MP40
Flow: 1000-3200gph
Watts: 9-28

It looks as though I wouldn't be able to turn down the MP40 enough if I needed it.

You are better off with the MP10, bottom line. If you ever go bigger than40, I will endeavor to sell ya the MP40 I have, (long story), but that is neither here nor there.

Here's a tip:
Stats don't mean nuthin, it is how the particular piece of equipments performs in your system, trust me on this one. But....................... in this case, the MP 10 is the way to go

 

[eww]

MP10 = 1500gph or 37.5x turnover in flow
MP40 - 3200gph or 80x turnover in flow

I guess it just depends on how much turbulence you want in your tank. Personally I would stay with the MP10 and maybe use 2 of them, one on each side of the drain end of the tank pointing toward the other. I would have them alternate so you have a variable gyre flow. The MP10's would also have a smaller appearance than a MP40 in your 40B tank. Just my opinion for what it's worth.

FUNNY... I was typing at the same time you guys were...

 

[dsmhero]

I agree on the stats should be taken with a handful of salt, I have had experience with this in the auto industry.

Now I have to figure out what return pump to go with. I need to complete the design of the return system to see what my theoretical head loss will be. Any comments on brands?

I like the idea of running two mp10's but does sound expensive lol.

 

[CarlaW]

I have had real good success with Mag Drive pumps, I used a Mag 5 on mine.

 

[dsmhero]

If I have time today I will design the return and give head loss stats on both the Mag5 and Mag7 and see which to go with flow wise. Have you had trouble with noise on the Mag's? I have read both positives and negatives.

 

[CarlaW]

You are gonna have "noise" with anything. I never paid attention because all of my stuff is downstairs, and out of the way. I am the wrong person to ask about that. Mag drive pumps do pretty well on head loss, you can look at Marine depot and the stuff they give is real close to true.

 

[DevonM]

My Mag 24's are pretty quiet as long as you place a filter pad underneath them. Dan's had a couple that have been a lot louder than others so who knows for sure. On the Vortechs, I really like the battery backups that can be added to them for 30 hours of power outage flow. I would go with a MP 10 and see if you need another one but I bet you would be good with one.

 

[dsmhero]

Thanks for the input Devon. I may have to try out the Mag's since they are so affordable.

Can you and charlie calculate what kind of turnover rate you are running in your tank, it seems like everyone recommends such a wide range for SPS.

 

[CarlaW]

I think I am close to 30 times an hour, it is close enuf for government work anyways.

Do you feel like you have more than enough flow? I am running 40x in my 12g.

 

[CarlaW]

I always ask my corals if I have enuf flow............................... and they seem to say yes. It isn't the amount, it is the quality of flow you have, remember that.

 

[dsmhero]

Here is a picture of the return setup as of right now. I am thinking it should dispense much farther down the tank. Any comments and questions? With my primary flow being an MP?0 - I want to make sure I have QUALITY eace: flow.

 

[CarlaW]

are you gonna run the pipe closer to the edge idf you dispense it further into the tank. Your MP????? is gonna be on which end again. I am sorry, I am old and pretty much decrepit, and have CRS

If I go farther down it will be tucked underneath the trim. Also, the return line is 3/4" and then narrows to 1/2" at the T-fitting, I hope that's kosher.

The MP?0 is going to be on the overflow side...so that way the far(viewable) end is unobstructed.

CRS?

 

[CarlaW]

How are you gonna hold the PVC up if you go further down the tank? If I am lookin at things right, the right side of the return will have less flow, (not much), than the left side.
