"Burping" gravel Also, read this
If it's toxic gas, you should be able to tell by the smell. It will stink to high heaven. It could be oxygen. If plants are growing well, they can pearl under the gravel, as well as from their leaves. But usually the bubbles aren't that big. And, aside from the chain swords, you don't have the kind of rooted plants that do this. Do you have a UGF? If so, then it sounds like what happens when you don't have enough gravel over it. I've had the same "issue" too, wouldn't call it a problem, the bubbles never smell... and I know I've got at least 2-3" of gravel.... and a UGF, but I make the bubbles, by using a wooden skewer and aggitate the gravel to release some "stuff" and every so often, if I take the skewer and catch a part of the UGF, I can pick the UGF up a little, and bubbles come from everywhere in that plate... I've smelled for the sulphur,but not present, never smells, and is rarely funky... actually, it scared me once, and a peacock came over and chased the bubble and inhaled it... spit it back out.... I was totally expecting her to keel over.... but she didn't.... Could it be just oxygen, because I have some good growers.... |

Air from the airpump used to drive the UGF is getting caught under the filter plates, and when there's enough of it, it bursts up through the gravel. Ideally, you want another inch or so of gravel -- enough so that the air doesn't pop up through the gravel. It's supposed to drive water circulation through the gravel, and if the air is coming up through the plates instead of the lift tubes, the UGF is not working as designed.
