Also got in my updated Eshopps M130 sump big shout out to
@ESHOPPS.INC for sending it out!! Love the setup and design of this sump!! Only thing that really bothered me on this whole m130 setup is how the overflow and pipe layout are designed..
So my largest issue is the fact that each drain in the overflow is male threaded with a gasket on the inside and of course a gasket on the outside.. the drain pipes under the stand are female threaded so your required to screw the drain pipes from the bottom which is almost impossible because the top pipe constantly spins.. all had a bur on the threads of the male end so it made tightening them down impossible alone and almost impossible without someone with a strong grip reaching into the overflow and way down for the main siphon and trying to grip the tube to keep it from spinning while trying to screw on the pipes from below.. absolutely insane finally got it tight enough after 5 busted knuckles that it wouldn’t leave but if I ever have to make adjustments in the future I will be cutting the pipes out ha! Ha with that said
My other issue is the layout of the pipes the instructions as the come don’t make sense and after talking with Eshopps I swapped pipes 1/4 so that emergency drain was not draining into Refugium
After looking at this design I was not that happy with it either because the main siphon which I have in 2 and Refugium siphon in 4 are both the same height and only about 1.5” bellow emergency overflow.. this didn’t make sense and sounds like it would be loud and difficult to dial
In without gurgling especially considering from my research I wanted my main siphon running to reef mat to carry about 90% of the flow and refugium about 10% of the flow so in the end I left the original main siphon which was about 5” shorter than emergency overflow
And the refugium drain I cut about 2 inches above the main siphon and 2” below the emergency overflow! Now after getting everything dialed in it is completly quiet
