Clear stuff growing in the fish tank?

It's impossible to say exactly what the clear stuff growing in your fish tank is without more information. To help you identify it, please tell me:

1. Describe the clear stuff:

* Appearance: Is it stringy, fuzzy, slimy, or filmy?

* Location: Where is it growing? On the glass, on plants, on decorations, or floating in the water?

* Texture: Does it feel smooth, rough, or sticky?

* Movement: Does it move or sway with the water current?

2. Tell me about your tank:

* Size: How many gallons is your tank?

* Fish: What types of fish do you have?

* Plants: Are there any live plants in the tank?

* Maintenance: How often do you clean the tank and change the water?

Once I have this information, I can give you a better idea of what the clear stuff might be and how to deal with it.
