Vibration dampening

[rooneyj889]

Hey all, I am currently setting up my basement sump for my reef tank. Today I leak tested the manifold and made sure the pump was running correctly. Everything is great except the sump is vibrating which is causing a lot of noise. Does anyone have any ideas on how to fix this?

I am running a BlueLine 70HD external pump and the sump is a rubbermaid 150 gallon stock tank.

You have 2 main things to play with here. The first is some sort of dampening base for the pump. Silicone hot pads are a popular choice. Second is a section of soft plumbing both before and after the pump. Silicone tube is a popular choice for smaller pumps, but sourcing larger diameters can be a challenge. You might consider spaflex.

I recently read that Blueline is out of the aquarium pump business due to the parent manufacturer shutting down their pump operation. I decided to snag an extra impeller and o-rings for mine. I figure those are reasonable insurance for a bulletproof pump.

Yeah, I am using flex pvc before the intake and right after the output and have a silicone dish drying pad right under the pump

Agree with the above. Silicone dish pads by Oxo have been great for me. You can buy a pretty big pad and cut it to fit your liking.

You can also buy sheets of rubber, thicker than silicone, at hardware stores. The pump may also need to be fastened down, through the pad, to a solid and immobile surface. This can help deaden certain frequencies.

Vibration dampening - Silicone hose

I've been trying to find a vibration solution for my plumbing. Does anyone know if this silicone material in the attached web link would be saltwater safe ? Temp and pressure are ok, I'm just not sure of material make up. My plumbing is 2" so its been a challege to find any 2" silicon like we...

Yeah, so I'm going to bookmark that tube now. I'm currently in a Rubbermaid stock tank, but that'll be perfect for when I start setting up my display.

Do you think the one inch silicone tubing from BRS will get the job done?

It'll let some water through, but they recommend upsizing your piping size for optimal flow. You certainly don't want to downsize on the intake side of the pump.

So then what size would you recommend and how would I connect it cause they are male threaded 1" adapters on the pump

I used a thread x slip coupling to a few inches of 1” pvc to a 1”-2” reducer. For this tubing, I’d install a barb on the end with a clamp over the silicone tube.
