Eshopps Overflow and RS-100

[CBrady001]

So I have decided to go away from canister filters and all biological filtration in favor of a sump mainly because I want to add more delicate corals to my tank, currently I cannot due to a sustained low level nitrate level.

Ok so first off I'm upgrading my skimmer, the one I have is rated up to a 60 gal tank (mine is 75) the new one is rated @ 100 gal. I also removed all large bio load fish from the tank.

The sump is on the way (Eshopps RS-100) I already have the Overflow box (PF-300) and the return pump (Lifeguard "Quiet One 3000")

Questions:

What is the best way to connect the PF-300 to the sump? the bulkhead fitting looks HUGE! Are there fittings that will screw onto these threads? should I simply slide PVC into it and glue it in place? if so what glue?

Should I use PVC rigid pipe or flexable tubing?

Will the Quiet one 3000 need to be regulated? will it empty the sump faster than the OVF box can fill it?

What is the best return nozzle back at the tank? a pre formed one or a long PVC with multiple holes?

Any advise is App'd!

Thanks!

I run the eshopps overflow box that you have. I bought a flexible piece of tubing a inserted a piece of pvc into it and then into the overflow bulkhead. It fit so snug i didnt glue it and its never come off. While that box says its rated for 300 gph , it can handle closer to 6 due to the 1 inch drain. I run a rio 1700 and using the rc head loss calc found that my return is pumping 476 gph and the overflow box does just fine in fact im sure it can handle much much more. For my return line i used a 3/4 inch piece of flexible tubing, looks like a large piece of airline tubing, and bought the eshoppes return fitting, which is just a hard u shaped pipe ( pre formed like you mentioned) that hangs on the back of the tank and has a flow deflection head. You could use loc line with the same results. Just make sure you buy the correct size tubing for your equipment. Your pump and overflow box should have specs that tell you what size tubing you need and whether its inside dimensions or outside dimensions ( ID or OD) hope that helps good luck

Ok but what size was the tubing you used? do you remember?
