Alright some pics...

this is the tank from the back. Where it is in my apt right now makes it impossible to get a view from the front.

I found this to be an odd overflow. It is a custom built all glass tank but I dont understand how the overflows work exactly. I am thinking of glueing some notched plastic to the inside of the overflows to be more of a surface skimming overflow. Anyone ever encountered something like this?

this is the view of one of the overflows from above. Flat glass...a bit confusing to me.

The inside of the overflow. It has 2 bulkheads for each overflow...why?
I think I may have gotten a bit over my head here as it was custom built and looking at it more closely (the overflows) it may have been done different from normal. It came with a little giant pump which looks to be unused as well. However I dont know the flow rate, it is a model 2-mdqx-sc 3000 rpm 131 watt pump...if anyone knows please inform me...I will be searching the web for an answer to the flow question. Flow is going to be a problem as the guy I got it from didnt remember or never knew the flow rate of the overflows. I still think its pretty awesome but I am getting a bit afraid I'm going to drown in the unknowns of the tank...
