This is my first attemp, what do you think? Any suggestions?

[glampka]

Looks good to me.

Thanks Gary, it's a 20long , I was thinking Lifereef overflow, and a mag 7. I have the tank, cut the baffles, have the silicon but can't find my caulking gun. Has to wait till tomorrow to get started.

Any thoughts on the Aqua-C EV180? or a better suggestion?

[NATIVEVAMAN]

That looks great to me. Good job.

How high will the return water be going & how many 90 degree elbows? You might want to consider a stronger pump if you want a 10X flow through the sump. For every elbow, you add 1 foot of head. Take a look at what the pump will be pushing at different heads: Danner Supreme Mag-Drive Aquarium Water Pump/Powerhead

Good choice on the skimmer.

[sgarron]

I was also thinking I could do this for a return, what do you think? It would be 1/2 inch pvc.

[glampka]

I like it. Should give good flow.

[yetta1.8]

looks good IMO, but shouldn't the baffles going from the skimmer section to the return be the other way around?

[glampka]

Good point - they should be switched - 1st & 3rd from the bottom, 2nd from the top.

[sgarron]

Thanks, that's what I thought too. But I was told the other way. Easy fix though since nothing is built yet.

I have the baffles cut at 8" high. Is that too high?

[yetta1.8]

just in case you wanted a little more info on sumps and stuff, take a look at this guys web page, the most info i've ever seen on sumps Melevsreef.com | Acrylic Sumps & Refugiums
unless you've already looked at it.

[glampka]

Don't think so but I would check what the required water depth is for the skimmer.

[e_baer]

you can always have the first baffle higher than the other.

[NATIVEVAMAN]

Two things about the second drawing.You might consider useing 1 inch pvc because you might not get much flow from 1/2 inch.I would also consider the idea of feeding the system from a third bulkhead near the center of the tank about 6 inch's below the static water line.With this configuration you could get about 1000 gph out 4 outlets.Then use your regular return for another 600gph.For a grand total of 24.6 x flow.this is exactly the system that I have calculated out for sweeties 65.I am also going to keep both pumps out of the water to reduce heat transfer to the water.You can also put loc lines in the fittings inside the tank to direct the flow righ where you want it.If you split the regular return line into two loc lines you get 6 points of flow.And its all done with no pumps in the tank or sump.

[sgarron]

Glampka, 4ft plus 2 elbows, rest flexible tubing. - Up to 9 inches for the skimmer.

Nativevaman, no bulkheads, it's a lifereef overflow (HOB).

Looks awesome (just like mine) !
Here is my build (shameless plug): http://www.reefbuilders.com/forums/r...-perfecto.html
BTW, I use the AquaC EV-180 (let me know if you need any tips in tunning it).

[NATIVEVAMAN]

I would be on my way to the lfs with 100$'s in my hand lol.Go get it drilled.

That would be perfect for the EV-180 which needs 9" so 8" plus water flow of 0.5-1" equals the 9" max. BTW, how talk are the sump walls going to be? you may be able to go higher with then baffles and build a stand for the skimmer. That's what I did. My sump is 16" high and my baffles are like 12 inches which means more volume and still plenty of room for overflow in case of power failure. Also the EV-180 is not that tall 20" I think (0.5" needed for cup removal) and I have like 24" under the tank. Just a thought.

[glampka]

The Mag 7 @ 4' + 2 elbows will be pushing only around 400 gph. Add to that your manifold on the bottom & you'll probably be getting much less than 400. The 9.5 will push 720. I'd go with the bigger pump.

[sgarron]

I could go with the 900 or 1200, but isn't heat a concern too?

[sgarron]

cela vie its a 20 long only 12 high. It's all I could fit and still have access to.

glampka, I could drill the sump and run a mag 12 externally, leaving only the mag 7 for the skimmer in the sump, and no pumps in the tank.
