buildup due to water cond?

I have a 20gal. fw tank and recently there has been a green and white buildup around the filters. it looks like lime or calsium. there is also some mold, but I think that's just because of humidity. anybody know what this is from?
:huh:

Green stuff might be algae. White stuff can be calcium deposits. This should not be evident for at least 4-5 months, unless you have a very hard water.

I have the same thing happening in a Whisper Power Filter. However, when I service the filter to clean all the tubing I also remove al the mulm that sticks around there,
 
I guess the green could have been algae, it just didn't look like it.
the tank has been there for about 2 years so I'm not suprised to see stuff on it.
