Good morning R2R, I have a question regarding my overflow setup. The tank is a 300 gallon dual corner overflow. The previous owner had it set up in a durso configuration. I am in the process of converting it to a herbie configuration. Each overflow will have its own primary and emergency standpipe. The primary standpipes are 1 1/4" stepped down to a 1" bulkhead, stepped back up to a 1 1/2" pipe and then they both go through an independent ball valve before they are connected with a T pipe and sent into the sock filter. My question is, will having them both connected into 1 pipe above the sump cause me issues when it comes to tuning them?
