I've been planning my sump build for awhile. The sump/refug will be a 20G long tank. I plan on using this sump for my current DT which is a 37G tank. I will be upgrading in the future to a 75G-180G tank, depending on the space i have in the house.

For now I have gathered a bunch of equip for the sump. So far, I'll be using an Aquamedic Turboflotor Multi SL protein skimmer which uses the Ocean Runner pump, and the return pump will be an Eheim 1260.

The first chamber will be about 10 Long by 12" wide by 9"H (this is where the intake is and mostly mech filtration / skimmer) the next 10" by 12" W x 9"H will be my refugium (w/ a DSB and Chaeto Algae). After the fuge, there will be 3" of space allocated for a bubble trap using three baffles, then the remaining 7"L x 12"W x 9"H will be for my return pump (which will house the Eheim 1260).

I will be using an Overflow Box for my current 37G DT. The tank isn't drilled but for my future tank I will be havign it reef ready. The Overflow box I got is a Lifereef Overflow Box (600GPH). The Bulkhead is 1" so I plan on buying the following:

which will be used as an intake tube from teh overflow to the first chamber and also used to return from 3rd chamber back to the tank.

I will like to add a check valve ( not sure the diff b/twn a Swing Check and a True Check Valve) between the return tubing.

Last item is to put in Ball Valves or Gate Valves (not sure which one) to control/stop flow, and where to place these valves to effectively control flow.

Will any unions be necessary for easy equipment access? If so, where will it best be placed?

It is actually a true union check valve that looks to incorporate a check valve and true union in one. I think ball valves are the way to go, and I think a union could be helpful if you want to do maintenance easily.

Also, just because I'm planning my sump almost identical to what you have, why did you choose 9" as the hight of the baffles? It's the second time I've seen that dimension.

[DaddyReefer13]

My sump set up is very similar to the diagram you have included. The height of the baffles was also a concern I had when setting mine up. In the end I settled at 9 inches because my skimmer required the water level between 8-10.5 inches. Also, the extra 3" was sufficient enough to prevent floods incase of pump failure.

good luck with your set up and hope this helps.

I chose 9" for the first baffle mainly b/c my skimmer is external or in sump but I plan on putting it external and for either, the outflow is at 7" H so I plan on doing 9" so their wont be splashing or water noise. The other sizes are 9" mainly b/c its easier to cut all four the same size. For it being 9" for the last chamber, I'll have more water supply in case I run out or if power fails.

MEE TOO 9" for all chambers excepy return 7" in a 20 long - 72bow DT

my sump is similiar too..(this is a basic deisgn for most sumps)but its 32x16x15 made from 1/2" acrylic
i have my skimmer compartment larger so i can change to a larger/different skimmer in the future if needed...the fuge is smaller but its only to grow pods and some algae..i have a phosban reactor to pull out the needed phosphates...im running a eheim 1262 for the return pump.you will want a ball valve/gate valve on the drain to control the noise of the falling water...and a ball valve on the return plumbing to regulate the flow going back to the tank...you might only need 1 union on the reutrn pump plumbing just so you can easily remove the pump for cleaning...is the tank a oceanic 37g cube?...if so...when you plan to upgrade?

[Hungriee]

great advice auto,
The tank is the worst tank ever its a 37G AGA tank. (30x12x23H). Thats one of the main reasons why I want to upgrade. I'll probably upgrade once I learn enough about reefs and have successfully grown out my current mixed reef collection before I move to a larger tank.

Just a couple of suggestions. I have built a ton of sumps...

Lose the bubble trap. It is totally unnecessary in your setup. The Chaeto will serve the same purpose.
This will allow you to expand the Refugium (More Export) or your return section. (Easier topoff.)

If it were me, I would increase the size of the return. This is assuming you are not using an auto-top off. As it looks now, you will have to add water quite often to keep the pump under water.

On bubble traps...after a couple of months they serve no purpose as the bacteria will cover everything and reduce the micro-bubbles to nothing.

[autoponicz]

the bubble traps is always a good precaution....
and an ATO should be used for any tank just for those few good reasons a ATO provides..
any microbubbles will depend on what kind of skimmer and how its tuned...some skimmers will produce microbubbles ...maybe because its not a well designed skimmer or the owner dont know how to tune it for max foam and min. microbubble ouput...
and if he decides to not use macro algae...then what is going to stop the micro bubbles...or his return pump is a strong one and circulating the water in the sump faster than the bubbles can dissipate...

i say a phosban reactor will work faster than using macro anyday....and you dont need an extra light....but having that extra natural filtration is fun

Thx auto,

do you have a pic of your sump/fuge
