Over Flows?

[NanaReefer]

I'm looking for some pics of actual over flows boxes in use. Visual learning so to speak

 

[eartaker]

Here are some pics of mine when I was building it...

 

[NanaReefer]

That is exactly what I was looking for! Thank you! How long are the teeth? See I'm wondering about the water level in the DT falling below the tanks frame. Which to me would be unsightly-lol.

I'm going to be upgrading to a 56g. 30x18x24 Single drain/return. I've NEVER done a drilled tank before so I'm a little nervous

Oh and I notice you have the center brace. Have you found this to be an issue as far as lighting is concerned?

 

[eartaker]

1.5" long and 1/4" wide. My water level sits right above my frame on the 75g. Its not an issue for lighting but I have 2 MH lights on each side.

i would take a dremmel tool and round all the teeth and mouth to increase the flow. teeth decrease the flow by half. here is a pic of mine i did recently

just my opinioin.

 

[senji]

oh and an overflow cap will reduce the algae growth in the overflow because it blocs the light any high oxygenated area will grow algae.

 

[eartaker]

Seems pointless to round the edges.... If the box can keep up with the pump then why would you need more flow in the box?

Teeth are not necessary on an overflow box. As Senji stated it will reduce your skimming by 50%
If you want to use teeth, the bottom of the teeth should be 1/8'' above the bottom of the top trim

if you go teeth-less, then your going to need to put a type of mesh on the top. the teeth help the fish and snails from going down into the sump. or the worse being cought in the drain tube. and causing the tank to back up.
if you have abnormally small fish you may want to use both.

A top would definitely be required. I have 2 FF and a Scooter Dragonet ATM.
I'm looking at this one possibly. I'd love to make my own but I don't have the tools.

There's also a smaller 700gph version that has a cover.
Along with the Eheim 1260 for the return.

I have another question about overflows.

I have two holes drilled on my 75g with 1" bulkheads. one hole will be my primary drain, and the other will (hopefully) be my backup drain. I was planning on putting in a 90 degree elbow facing up to near the top of the tank (above the water level) could I forego the overflow box on this since the drain level will be above the overflow level anyway?

Im not sure by your post, but it doesnt sound like your tank is drilled yet. If thats the case you can check glass-holes.com.

Glass-Holes.com dope aquarium stuff

If I understand you right then the answer is yes it will work. You just put a strainer on the drain pipes. But, you will not be skimming off the top layer of the water column which is desirable. so, in the end....go with the overflow box...and I'm a yes teeth kind of guy for the reasons previously stated.

The upturned elbow outside of the overflow box would only be a backup drain incase the main line is blocked. The main drain would still be in an overflow box which would be skimming of the top layer. What would you suggest for a strainer? plastic mesh of some sort?

 

[mercenary-grunt]

they make strainers. or hardware cloth. or Window screen.

If you use window screen or mesh, make sure you have a good cover to block out the light otherwise your going to have to clean the screening of algae growth frequently to keep it from clogging. I would use a strainer instead of a screen type material.

a strainer is not needed in an overflow box. but here is a link to what i was talking about. Intake Strainers, MPT Threaded - AquaCave.com
