I am at a stage now where my tank has completed cycling and got minimal livestock, before I stock up and start adding a lot more biomass I want to get my sump/mini fuge going.
I am comfortable with doing the drilling etc, however the issue I have is what size diamond circular hole cutters I need for what size bulkheads.
My intention is to have one 3/4 inch overflow 5" from the plastic border at the top of my tank and another at 2".
Then a hole on the other side for my return from the fuge at 5".
So, if someone could advise primarily: Where is the best place to buy these fittings(online), which sizes I'd need, what drill bits I'd require, good affordable return pump and any tips on noise dampening from the overflows.
Thanks in advance
My tank is a roma 125, 2 common clowns, 1 blue damsel, small coral frags.
I intend on adding a 25ltr mini fuge and fittings hence this article.
