Fish Tank PLAN!!!

Yes guys, here it is. After many a puzzling comment about the fish tank and chimneys and oxygen and dead fish and all sorts of things, I'm posting plans for the fish tank on here so you can rest at ease:

Alright, so there's the top view, and the side view, with a close up of the filter mechanism in the back.
Alright, so from the top, we have a right angle triangle with perpendicular arms 75cm long. The right angle (which will sit in the corner of the room) is empty to allow for cables to slide down the back. The next compartment out is the filter, which is built into the tank. Next is the area of the main tank, that is open to allow access to the tank. And the rest of it is the section that is covered by a perspex ceiling.

Looking at it from the side you'll see that the perspex ceiling is slightly tilted to help bubbles flow up the opening, and the access area and filter extend upwards into a short "chimney" which allows the water level to extend up above the level of the ceiling.

The filter is quite simple in design; there's some holes in the bottom right which allow water to flow from the main tank area through the back wall into the filter area. The water will then flow upwards within the filter through some filtering sponges. Above the sponges a water pump will pump the water across to the next compartment. The water can then flow up and down through various filtering media and other things (like water heaters and bubble rocks) until it's reached the left-most part of the filter. It will then flow up and over the perspex separating the filter from the main tank area, creating a small waterfall back to the main tank.

Before you people jump in and point out the flaws, yes I realise that the water levels I've drawn in the filter aren't level, and yes I am aware that they will level out. Please people, I know I don't know that much physics, but I know a little bit.

This tank plan has been very much inspired by the tank we currently have, however on a larger scale. Here's our current tank, for those that haven't seen it:

The "chimney" extends up within the burnt orange housing, meaning that when the housing is in place, you can't see the water level. You get a lovely uninterrupted view through the top into the water, and it looks awesome, as you can see. Lights are also held up inside the housing, and as is the filter. all cables run down inside the housing down the back of the tank, and come out down low and out of sight, very classy.
I will also build a similar housing for our tank hiding away the chimney, and also containing the lighting for the tank.
Ok, I'm not attempting the cantilevered design that this tank has (wouldn't recommend it with perspex) but I am bringing some improvements to the design. Namely I am tilting the ceiling of the tank slightly, so that air pockets down get trapped. One problem with this tank is that you get big air pockets in the highest corner every time you do a water change. Also of course I'm integrating a filter into the back of it, which will save a lot of money over buying an off-the-shelf filter.

Alright guys, hope you like the design, feel free to point out flaws now.

    I think it is alright.
    How big is the filter meant to be (as in thickness/width) when compared to the tank size?

    From an aesthetic point of view, there is a flaw with a triangular design in that you only ever are really capable of viewing from the front of the tank unless viewing from some funky angles.
    Of course, that probably does not really matter all that much... but... just saying...
    ...
    Unless, of course, it is put in a corner and that is the intention.

    All-in-all...
    Pretty :)

  2. Hi Travis,

    I'm not sure as to the exact dimensions of the filter just yet, I really need to do a thorough measuring up of all my sizes so I know exactly what how big everything will be. I'll get back to you on that one.

    The tank is designed to be put in a corner, hence the right-angle triangle design. Actually if you go to an aquarium store, increasing numbers of tanks are designed for corners.
