Plumping 29 Gallon

[Go Hooter Go]

Well this is what I am looking at...

Anyone see any objections??? Or questions?

yeah, why is the retrun going out the side of the sump instead of straight up? that would involve putting a hole in the side of the sump unneccissarily. also a right angle like that adds head pressure, so then you have to compensate with a larger pump to get the same flowrate...doesn't make much sense

also, realize that a 10 gallon sump is VERY small...I have a 20 long as my sump and THAT is pretty tight with the fuge, skimmer, heater, intake and return all in that space

That is the biggest that will fit under my stand. Yea, It sucks.... Well I'm still pending on the design of the Sump, and it could change depending how I see things fit in there.... Should be a few days on that.

I am thinking that a mag 9 may be too much pump for a 29. The return for my 29 has couple more elbows than yours, and I am using a mag 7. It is only running at about 3/4 rate, and there is a lot of flow in my tank. Just curious why you chose a 9. You may only get around 300 gph with a 7, but I would think that would be more than enough... Maybe some others with more experience would have some input.

I think I'd figure a way to put a 20L in the space and use the direct return route like adam says. Then cut the pump back a notch and still have tons of flow and maybe less noise from the water flow. Maybe a couple Hydors at the returns to vary the flow in the tank.

Go with the mag 9. That is what i have on my 29. I have two drains going down to my sump and then over under over for the baffles with a mag 9. I used the 9 because i wanted to get rid of the power heads in my tank. at that head I believe I have about 700gph going through my tank which is about 20x tank volume. It is pretty good and sometimes I wonder if it should be more.

Now with a mag 9 you will not really be able to add the refugium to the sump, and you will be fighting micro bubbles. The water will be moving to fast for anything in a refugium to sit still. Also you will need to have a better baffle system. Again because water is moving so fast through a small such a small sump you will be fighting microbubbles.

I have a 16g sump(homemade) that is still to small for the amount of flow going through it. I manages to get the bubbles under control but it took a lot.

I think your baffle configuration will cause problems. But definetly a good idea for the swing check valve over the pump. Much saver than drilling a hole in the return to break a siphon.

Not if you get a bit of gunk on the valve seat and it doesn't seat-- will just cause a slow flood rather then a rapid one... I'd use siphon breaks or both.

Agree that is too much flow for the fuge and you might have bubble issues--- these can help with bubbles if you run that flow

I bought 10 for $30 shipped to my door.

Have you considered slowing down the sump flow and running a closed loop with the mag 9 for flow..

I must respectfully disagree with this. A swing check valve would be much safer than just siphon breaks. There is to much of an issue with coraline, algae, snales, detritus, anything really clogging the holes. If you fear one than use both, but I wouldnt go with just the holes. A swing check valve, while it may need maintenance, less than the holes.

I have heard too many bad stories of check valves going bad. Just add more siphon break holes and everything will be fine.

I have 30 gallon and my return is just far enough down in the tank that the sump will not overflow if power goes out. I don't have any hole in it for a siphon break.

Well the deminsions below for maximum space is.... 20" Long, 11" Wide. and Up to 18" Tall....

Sorry I was going off the 31" dimension at the bottom of the diagram... plenty of room in 31" for a 20L.

 

[Go Hooter Go]

I wish, but what you can not see is that the 4 corners come in 5" x 3".... So you take 10" from the Lengh and get 21"...

2x4's were placed there, and out side was built with 1/4" Plywood.

I forgot to design with Sump in mind. I can't put a sump anywheres else, not thru the Floor because there is no floor below it lol. Ummm...
