Worrying pink slime on airtube, dangerous or just dirty?

I have a 30cm airstone in my tank, and regardless of my attempts to keep the tank nice and clean, the tube to the airstone always seems to get really slimy and gross.

I know this is possibly regular and normal, however I was away for about a week and had someone else feeding my fish, so the tank wasn't cleaned at all throughout the week.

When I came home the airtube had a really digusting pink layering over it. It's not the first time it's happened either, so since it recurring I've decided not to put the airtube back into the tank until I can be certain it's safe, as I know that a general rule is that pink grime in cleaning things like bathrooms is usually dangerous bacteria, so I don't know if the same applies to fishtanks or what not.

I thought you guys would have more of an understanding than I, and lucky for you I posted a photograph so you don't have to rely on my terrible description. Here it is.

Any help is appreciated! Thankyou!

Never had pink in any of my tanks but I recently went to a small pet store that had these quarter sized pink bacteria blooms that looked pretty nasty. Easy advise is to spent $3-4 and buy a new airline tube, if the pink isn't anywhere else in the tank then it might be something about the rubber of the tube, try finding some nice blue or black air hosing marketed as silicone. Maybe blocking the light with a colored hose will prevent it from coming back

Ah okay thanks man. When I first got the pink stuff I just cut the tube, because it looked nasty. But now there isn't enough tube to cut so perhaps you're right in suggesting a new tube! Interesting to see if anyone else has had this before though. My fish is still quite healthy though so I don't think it has done him any harm :)

Thanks again mate!

lol np hopefully someone else will have experience with it for you to go off of

That always happens on my airline tubes as well. I think it has something to do with the clear rubber they're made of. I have two bubblers in my tank, and the one with the black rubber line never gets gross or develops any algae. It seems to be a higher quality rubber, more pliable and durable. Only a few $ more expensive than the clear variety as well. That said, try to find the black tubing to replace that with and see if that solves your problem. :-)

Ah awesome! I wasn't as concerned before my girlfriend told me that pink generally equals poison in the world of cleaning. I'm glad it doesn't seem to apply to fishkeeping! Phew.

I'll grab a black one and let you guys know how it goes.

Though I'm not overly concerned as my Angelfish doesn't seem to be a huge fan of the bubbles. In fact I think it kind of stresses him out so I rarely use them. Is it something I should try condition him to, or just not bother?

I think your girlfriend is correct. There are phosphates in tap water, which causes that pink slime (Serratia marcescens) to grow in your shower, around the drains, etc. I believe it's the same thing.

Linkie to wiki: Serratia marcescens - Wikipedia, the free encyclopedia

Nasty! Glad I kept it out of the tank then. You would think that they wouldn't sell those types of tubes if that kind of reaction was possible hey.

Airline tubing is cheap. Especially the clear kind. That's probably why. They know you'll end up replacing it.

Are you using a good water conditioner in your tank? How about beneficial bacteria? I noticed that's a lot of pink slime. When I get that on my airline tubing, it takes months for a tiny amount to bloom. And I mean, just a bit of pink haze at the water line.

jono088 06-21-2012 08:08 AM

Yeah it was quite a lot which was what concerned me.

I use API Stress Coat in the water. No beneficial bacteria, is this something I should be using?
