Well I finally found a $1.00 per gallon sale at petco tonight and got my 40 gallon breeder tank for $42.00 and some change. I been looking at a ton of other peoples sump designs, and seen some very simple to some that are very complex. My goal is easy to maintain. I made a rough sketch if my idea. I'm open to any suggestions you sump pros got.

Water comes down the display tank from a CPR hob overflow rated at 1,500 gph. Will flow down to two CPR filter socks that are 200 micron. I have to trim the top black trim piece so I can put the filter sock holders side by side. If you look at the pics you can see the trim won't let me set in place correctly. Water will flow up and pour onto a water polisher pad that will be in an easy location to change most likely once a day. From there it will trickle down over my bio media some will be out if the water but most will be submerged. From there flow into my refugium with 4 pothos plants. Now I'm still up in the air if I want to do a second bio media are before the return pump, I think if I do I will use pot scrubbies. The return pump will be a Laguna max flow 1500gph at zero head hight. I will have a 3 1/2 foot head hight so that should put my return at about 1,300gph. As far as chamber sizes I'm waiting on the return pump to get here so I know how big the return chamber has to be and I will go from there for the rest of the sizes. We'll let me know if you have any questions. Tank is a standard 180. Heavy bio load. 3 oscars, fire eel, black ghost knife, and soon goldie pleco. I am also running an fx5 full of pond matrix. Please note that the fire eel and ghost knife are in a separate tank at the moment. And I don't have the pleco yet. My water tests show perfect with my nitrates around 20 ppm with one 30%-40%water changes a week. Thanks for the input.

Looks good for the most part. Id put the submerged media right in front of the pump inlet and skip any other bio-media. I'd skip baffles too. They just make the sump harder to clean IME.

The 200 micron socks are just about useless in my systems. In my systems that run 2 socks I use a 100 and a 50 and it works very well. Occasionally I'll throw on a 25 to really push the clarity.

Here's a few pics of the 75 gallon sump on the 300 and my newest build, a 135/75 with full refugium/sump planted and stocked. Bio is packed inside the black pvc fitting. You can see one of my festae grow outs up front lol

Ya I got 2 100 microns socks on the way. I would like to put a 50 micron polishing pad over top of the bio media to help keep it clean. It will at on top and be very easy to change out. As far as the baffles, I was going to not use them but I wanted to direct and sort of slow the water down when it gets to the roots of my plants.

I'm a little stuck on how to plumb this. I was just going to use flexable hosing but my local hardware store (lowes) does not carry large enough tubing, to fit my bulkheads. How hard would it be and would I lose any flow with hard pluming? I would have to use some 90 degree elbows and that should slow my flow down some right? I'm trying to get the most flow out of this sump as I can.

I hard plumbed the drains on both systems. The 300 is a dual Herbie setup running into a single 2" line and gate for water level control(in the boxes) and the 135 is plumbed Bean animal style. I figure about a foot of head per fitting usually. Most Lowes carry flex up to 2". I got mine here.......http://flexpvc.com/?gclid=CKTxoK-KkbwCFWJo7AoddnwAdA

What size are your bulkheads?
 
Pothos can make a little bit of a mess with leaves falling off and what so just be ready for a little cleaning with the plant in your sump.

As far as the pothos, I have had them in my 90 gallon now for 4 months and they already grow a good foot and a half. So as far as them dropping leaves I'm at the stage now where they should be ok. But ya I'm ready to clean. Lol.

Got the black trim cut and filed down and the filter sock holders now fit the top of the tank.
