Now the Hardware Part
Here it is the original sump diagram
Once built it had to be corrected due flow risks and problems
the front will serve as a refugium...
the back is designed to hold a g2,g3 or g4 skimmer
and at the very end it is the return pump area....
I tried with a MAG 36 but man that is too noisy
I guess i will go for a Mag 18 or 24 or perhaps 2 rio 32HF
the corrections made were done reducing some of the inner heights
