Congrats on new tank...
Congratulations on that beautiful tank!!! Best of luck with it. I'll live vicariously through you with your tank
What made you decide on the Hydor Seltz pump? I have been going back and forth so much trying to decide which pump that I went ahead and ordered a jebao 10000 for now, and will make it my back up pump when I decide.
What size pipe do you have coming out of the pump?I have a Hydor 2400 on my acrylic tank and it performs nicely. It has a high pitched whine, but not too bad. Limited features (5 speeds, one 5 min feed), but for the money, I think it's a good DC pump. I would have gone with COR, but the reviews are horrible, the flow rate isn't great and they are pricey.
That is where your noise is coming from, backpressure. You need to increase your output to the maximum possible 1.5/1.4 inch and gradually reduce to the tank. This will increase flow and eliminate noise.3\4", which admittedly has inherent flow restrictions.
Those pumps are virtually quiet, when plumbed correctly. You have it reduced down really small, so I think it will make a noise on any speed.Point well taken, but I think the motor itself has a certain sound regardless of back pressure. For example, there are five speeds on the pump and it has the same tone regardless of which one is chosen. You do hear the increase of RPM associated with each and a slightly different pitch. So, the whine is not annoying, just present.
