Forgive me if this has been discussed but did not see it. I have not done a SW tank in about 15 years and preparing for it once again (pretty much starting over from scratch). I am close to pulling the trigger on a SC 120 and it looks to be setup for a Herbie overflow. My question is this... Would there be any issue with converting this to a bean animal and run the return(s) over the top (other than aesthetics)? Are the holes appropriate size for that setup based on that overflow setup and size of tank? Is that conversion not even worth the hassle? I would like it as quiet as possible and while Herbie is pretty safe, I really, really don't want an issue and a wife who would likely kill me if I had a terrible situation (redundancy = marriage). The plumbing is still something I am trying to wrap my head around as far as flow rate, gph, optimal turnover, etc. Any help for a noob is appreciated
