Potential danger! whisper air pumps
Buyers beware! A couple years ago I bought some air powered filters, and a whisper air pump, model 100, to power them all.

After a while the air pump kept putting out less and less so I eventually gave up and went to individual smaller pumps.

I have in the mail as we speak a new sponge filter for my 55g. I dug out the forgotten whisper blue dome, and decided to see if it was worth fixing. Removal of the cover was shocking. With the potential for it to literally be shocking. The wire was pinched almost all the way through, with the insulation sliced away in several spots on the 2" of wire between the housing and what I will call the motor.

The wire was cut on the neutral side, and the hot side was pinched, but the insulation not cut. If it had, it could have very, VERY easily started a fire. Or shocked me when I picked it up to move it. I, for one, dont believe in isolated incidents regarding quality control.

A second note, both diaphragms were ruptured. It was only in service for a few months.

The moral of the story... If you own a whisper blue dome, throw it away and replace it or at the very least remove the cover and inspect it!

Sadly a lot of aquarium equipment I take apart shows really poor quality standards. I can't see how half the light fixtures I've taken apart clear safety measures. I'm pretty sure thats why a lot of aquarium equipment says unplug before handling lol.

I've got two of those air pumps running in my room. I recently bought them (like past 3 months). Should I be worried? :-?

I was going to buy an air pump this week, thanks for the heads up!

I have a Whisper 60 that puts almost no air out of one of the ports after less than two months of use. They're also not that quiet if you ask me. I regulate bubblers by bleeding unneeded air from the gang valve, I don't have excessive back pressure. No reason it should have failed that quick.

Common sense! send it back as maybe it is an issue they are not aware of! Manufacturing problems do occur.

I would strongly advise people AGAINST opening up electronic equipment you are NOT qualified to can be deadly.
Just an example it takes a very minimal amount of electrical current to fully stop your heart, your TV on average holds a 5000v charge for up to 15-20 seconds after you turn the power off!

I would definitely be worried. Not that they are going to cause a problem per se, but like i said, poor quality control is NOT an isolated incident. There are 2 issues here. First, I would remove the 4 screws on the back and remove the blue dome, ensure that the wire is in the grooves and not pinched. They sell rebuild kits, so they are user serviceable. Just ensure they are unplugged, as you should anything. As tazman says, If you dont know what youre doing, I would just return them or replace them, if it were my choice.

The second issue, is their longevity. I have 1 that failed after only a couple months due to blown diaphragms, and for the cost of the diaphragms, I can buy a new fusion. I have never met anyone who has had one of the newer blue dome styles that has lasted.

Oh wow. I'm certainly not qualified to work on this things. I'm a biologist not an electrician. As I use bubble filters what air pumps should I get to replace them?

I have had good luck with fusion, personally.

I know some swear by luft pumps, but I have no experience with them.

What about the Rena pumps? I only have Petsmart and Petco near me, and that's all they carry. Anything not in those stores would have to be ordered online.
