Ok guys, I have been doing plenty of research on this topic now, I have come
up with a master plan,
THIS PLAN HAS BEEN SHOT DOWN BY THE GUY I WANT TO BUY THE TANK OFF - WE'LL
GET TO THAT SOON.
I'm going to silicon a piece of perspex/glass in the corner to form the
triangle as we have already discussed. In the bottom of this piece of
glass, will be two or 3 holes drilled, just above the substrate level for
water inflow.
This will rise up the column with the assistance of an airstone, providing
some extra lift.
From here the water will travel down a "stand pipe" which will fall down
into the filter below the tank via a hole in the bottom of the tank. The
stand pipe will have a "slurp and gurgle" prevention measure: a t-joint and
an elbow so it will look like this:
______________
~~| ~~~~~~~~~~~~~ |~~~~~~~ Water level
| __ ___ |
| | | |
| |
| |
| |
| | |

to sump
I was thinking of having two of these in each back corner of the tank , and
joining up with a t-joint at the back of the aquarium. I imagine doing this
I will have to experiment with the inlet holes in my piece of perspex to
ensure I get a good enough "suck" to pull through enough waste.
I want to then get another bottom hole drilled, for the water inlet.
The advantage of this is that everything is nicely contained and there are
no pipes hanging off the tank anywhere.
BUT! THE local aquarium manufacturer reckons putting even one hole in the
bottom can damage the structural integrity of the tank, and these holes will
not be able to be drilled right near the side of the glass because the main
support beams of the wooden stand are directly below the sides. fair enough
I guess.
He recommended just cutting a whole in the side of the pipe and using a
swivel-able elbow joint inside the tank as an inlet, to control the water
height. (his hoods cover the top 30 mm of the tank ( ~ 1 inch) so I can
hide the water line.)
He didn't like the idea of the perspex triangular prism in the corner but I
told him I would be doing this anyway.
so that's where it stands now... I'm really enjoying this project but I am
starting to look forward to talking actuall fish with you guys soon!!!
So looks like that is how it will end up.
