Wish I do more research before I purchase my return pump, Syncra SDC 9.0, for my new Red Sea reefer set up. I read some of the sale ad syncra is a very quiet pump. However, after installation, it emitted a constant loud annoying hum. I changed the tubing to a reinforced silicone tube directly between the pump and reefer inflow adaptor and also wrapped a silicone pad over the pump with no improvement of the noise. Wish I bought vector 2 instead!! Anyone knows a good way/trick to reduced Syncra pump noise. Please help!

Did you put the rubber feet on the pump? They were in the bag with the plumbing connections. A reinforced silicon tube is still very rigid. I have some plain silicone tube running from my two Synchra 9.0s for a couple feet to my tank hard plumbing and they are very quiet
Thanks. Yes, rubber feet are on the pump, will try to look for some plain silicone tube at Amazon. Is plain silicone tube too weak and may lead to rupture?

BRS sells that tubing: https://www.bulkreefsupply.com/white-soft-silicone-tubing-sold-by-the-foot.html
I've used it for years and never had any issue with it weakening. That being said, I only run about 1000GPH through it and only for about a couple feet at the longest. I also don't use it to plumb directly to my UV because I'm nervous the light spray will weaken the tubing. No idea if that's a real concern, but I figured better safe than sorry!
