Asylumdown's 275 Tank build

[asylumdown]

Did a quick sketch of the tank. It's not even remotely to scale, but here's how the drains/overflows, returns are going to work.


Two overflow boxes on either side of the tank, each with two holes. The left side is directly above the return pump in the cabinet, so the holes will be a drain and the return. The right side will just be a drain and an emergency drain.


The return will come up above the overflow box and run over the centre of the tank. Since my canopy is completely enclosed and I'm likely going with modular LED lighting, the centre return line shouldn't (I hope) interfere with the lighting. This design also reduces the number of holes I need in my tank and thus the size of the overflow boxes, and it gives me the ability to distribute flow towards the centre of the tank, or to specific dead spots that the vortech's might create.

I will also need 2 return drains and an emergency drain to become completely blocked before I have a flood.

Not sure if I should go with 4 MP40's or 2 MP40's and 2 MP60's though, anyone have any thoughts?

I can't believe I missed this build until now, absolutely stunning so far, I'm stoked to see it filled with water!

Have you finalized on internal overflows yet? My biggest relief on my new tank was finally getting rid of my little bastard of an internal overflow. They are bulky, take up space and are a nightmare when it comes to maintenance (leaky bulk heads, fish overflowing in, ect...).

Another major problem you run into with side internals is that they block valuable aquascape and swimming room.

In the amendment below the red areas are places you wont see when you look at the tank, yellow is area of high flow and blue is your flow pattern.



By having your internals placed as such your loosing a whack load of valuable real-estate, another problem with placing them there is the final placement of your MP40W's. When you confine the MP40W's to a small water foot print (with the overflow box and the rear/front tank wall on either side) it restricts the amount of water that can be drawn into the pump decreasing there efficiency.

If your set on internals you could do this:


Or if you really want to shake it up and go external you could coast to coast it like this:


I will post on the radions after I eat supper, quick overview though: GET THEM! .

I'm pretty sure your proposed overflow boxes would be blocking a visible pane. Maybe I'm not reading his drawings right but this thing is viewable on two sides is it not?

Gah, sorry I thought it was like this with one single viewing pane.


If that's not the case ignore all my crazy ranting please haha .
