Faq – About Aerator Faucet

Nancy asks…
What’s the difference between a Slotless and slotted faucet Aerator?
I’m about to buy a replacement on lowes.com and need to know what is the difference.
Thanks!
Staff answers:
Well for one its the price and the other is the type of flow exiting the faucet. A slotted is more common versus the slotless. Slotted produce a finer , smoother flow……..

What is the purpose of an aerator on a faucet?
It is recommended that I remove the aerator from my faucet before attaching my new aquarium python system (http://www.pythonproducts.com/aqprod.html ) up. That should be pretty easy. But I was wondering, what is the point of that piece on the faucet? When it comes to fish keeping, it adds to the problem of supersaturated nitrogen bubbles in fresh water, requiring more water aging. Can I leave it off?
Staff answers:
Aerator adds oxygen and pressure to the water. You can leave it off but faucet will probably be week.

James asks…
Chemical smell Coming From Bathroom Faucet – Green Balls In Aerator?
Last year we put in a new bathroom and we noticed a few weeks ago a chemical smell coming from the facet. What’s weird is that the small ONLY affects the bathroom faucet and no other part of our place. I took off the aerator and noticed a few green granular balls right on the aerator. I removed the balls and the smell drastically improved for a few days, but the smell came back and now it is worse. The smell has a more of chemical smell like grass. The smell comes from both hot or cold water from the bathroom faucet. What makes this unusal is that the faucet is only 1 year old and the bathroom was gutted out a year ago.
Could the smell be coming from a corroded faucet or pipe?
Any ideas appreciated.
Staff answers:
Normally there is a smell that comes from the soldering or gluing job the plumbers did on the pipes, and it takes a few weeks to run out of the pipes. But that would have been gone pretty quickly. I’ve never heard of green balls except when someone has a filtration system that blows out. Why you would have a filtiration system just going to your bathroom, I don’t know, but I highly doubt it. Besides, you would know if you had a filtration system. I’m not going to say this couldn’t be from a corroded pipe, because it’s possible, but corrosion generally doesn’t have a smell, especially not a chemical one. This is the strangest plumbing question anyone has ever asked me.
Do they look like this:

If so, you could somehow have an algae growing in your line. That would explain the chemical smell. Here’s a description I pulled off a website:
Slimy spheres on the bottom
Gelatinous balls seen on the bottom of lakes, especially in clear lakes where light reaches the bottom or in shallow, calm waters, are colonies of Nostoc, a blue-green algae (cyanobacteria). While they look slimy, the balls are fairly hard and tough, and can range from a fraction of an inch to larger than a golf ball. These algae are not a concern and do not indicate bad water quality. They are also sometimes seen on damp forest floors and in ditches.
Keep in mind, though that this is from a wesite concerned with the water quality of ponds and lakes. How old is your house? It’s possible you might have roots growing into your pipes, causing accessibility of plantlife. Let me know what you think.
