My Filter Is Making Bubbles?

[little_mermaid]

Hmm today I noticed a bubble nest in Loretta's tank and at first I wondered if they were hers, but they are much too big I think...and tonight I took a closer look and it looks like the bubbles are coming from the outflow of the filter...what would be causing this?

I've noticed that if the bubbles tend to build up and not just sit on top of the water but start to look like little tiny mountains of bubbles, it's generally a bubble nest.

If you have a low current filter, and the water level is right, bubbles that look like a bubblenest can form by the outlet. There is enough water disruption that bubbles form, but the filter current isn't really strong enough to disrupt them. This is especially noticeable in a new tank that is cycling because if there is not a lot of surface disruption, a film can start to form on the top of the water that holds the bubbles.

I have caught a couple of my guys building right next to the filter outlet and right behind it though. This is really where the least amount of current is in the tank and gives them something to build against. When the nest gets big enough, it gets pulled forward a bit (to the outflow of the filter).

If you can post up a pic, we could probably tell you if it is a bubblenest or not. ....Although bubblenests vary quite a bit.

Inadvertently posted a pic for something else in another thread and realized that it entirely relates to what you are talking about.

see my pic in this thread and look at the filter outlet:

Thanks, but for some reason that link didn't work; it sent me back to the forum's main page.

Well that all makes sense...I didn't really pay that much attention to it this morning, and when I got home from the LPS I cleaned the whole tank out (note: I did NOT change the filter).

It's just good to know that it wasn't something I needed to worry about apartently...
