help...durso or herbie
I am in the middle of setting up my 300dd, it didn't come with the overflow so I want to get some opinion on wether to do durso or herbie.
I have durso right now on the tank that I made out of 1.25 pvc, beside the sump being a wave pool I really don't have a problem with durso overflow. I also ran a filter sock on the sump so it is near silent. The main reason I want to go with herbie is due to turn over rate in the sump, so the question is will herbie give me more flow or is it gonna be the same as the durso?
From all my research it seems that the flow rate really depends on the wether the inlet teeth of the overflow beening restrictive or not and the size of the bulkhead you are using. The 300 came with 1" bulkhead so really doesn't matter what I do it can only accommodate 600gph per bulk head. So is it worth it to lose my hidding return line for the extra emergency overflow design on the herbie and get more flow or am I just wasting time and effort for no reason. keep in mind that I am okay with noise level of the durso and the turbulent water in the sump.
