What is the stuff growing in my gravel?

Badmans Tropical Fish Message Center: Tank health and maintenance: What the stuff growing in my gravel?

I have a 20 gallon tank with an undergravel filter. The gravel has white stuff "growing" in it. It clings to the gravel and makes it clump together on the surface. Anyone know what it is? Is it something I need to get rid of...or is this normal? I have had the tanks for over a year, this is the first time I have seen this. Please let me know...

What does this stuff look like - colour and texture?

It is whiteish when it grow above the gravel, and binds the small peices of gravel together below the rocks. I can pick a clump up and get some of the gravel off, but it clings really well. It is soft. I don't know know how else to describe it...

OH MY GOSH - THAT'S WHAT I HAVE!!!!!!!

Go and check out my post in the General area. It sounds like it might be bacteria (perhaps living of excess food) and could be a sign of deteriorating water quality (hope not!). I just use the gravel siphon to get rid of it. Plus that will pick up any decaying food that it's feeding off. It's interesting how you've had your tank set up for over a year and I've had mine for about a week and we both have the same problem - it makes you wonder how many other people have it without realising it. I only noticed mine when a I shone a torch into the tank (I don't have tank lights yet) to see that all was well (and as it turns out it wasn't!). I'm so glad I found your post!

Sierra & Beth, I posted something about this in Sierra's post in the other section. Most likely fungus, but you can continue the thread there.

Thanks for the info. I appreciate your answering my questions. I did a partial water change again this week and have cut back on the food. I have mostly bottom feeders in my tank, several cories and a small clown pleco, 2 rainbows are the only other occupants. I had been feeding some type of sinking pellet everyday. thanks again!
