I know it’s kind of a dumb question but I just wanted to know how others had their sump plumbed and share my idea for mine and take any recommendations on what to change or add. So I’m planning a 29 gal reef tank with 20 long sump under it. I have a drilled overflow box rated for 400gph. I was planning on using 3/4” hard plumbing for the overflow and emergency overflow. One 90° Fitting to go into stand and then another 90° fitting to go down into sump for both. Including a valve on the overflow to control it for any reason. And then on my controllable return pump run 3/4” soft silicone tubing almost all the way up and then change to hard 3/4” pvc for the return assembly. I’m using a bulkhead that’ll go to loc-line hose and then a loc-line flair. A couple questions regarding this. First off, how does that plan sound? Second off I’ve read the soft silicone tube on return makes it a lot quieter so will I lose any of that silencing affect by switching to hard plumbing? Do I need a check-valve in my return? How do I switch from soft tubing to the pvc? I’ll take any recommendations or opinions or just showing off what you have set up. Thank you!
