your bracing question can be answered by your tank maker. Take for example, if you go coral reef to make your tank, they can do it braceless and give you warrant. for your overflow box, it is the same. it will depend on your supply and return pipe size. good to have 2 supplies and returns. for supply can go for 25 and return 32. the bigger.they are, yyou have.more choice for return pump. for silence operation, incorporate durso pipe and also ensure yr return pipe to the dump has valve to control. hope this help.
This maybe resolved by drilling holes on your return pipes but u must also make sure your water volume is not much for your sump to handle. This can also be solved by changing your return pump to a lower flow rate type. Hope this help.
