You need to use a siphon to clean the gravel (while in the tank, don't do anything crazy like take the gravel out for a deep cleaning) You just want to siphon up the loose poo and excess food, and in that process remove about 1/3 of the water once per week. It looks clean, but there is fish waste there that will break down and make the water toxic if you don't do a regular clean-up. Don't do a major cleaning-- the tank *needs* bacteria that naturally occurs and helps to keep toxins from building up.
Be sure to use a water conditioner in the water you add so as not to introduce chlorine to the tank. I keep a 3-gallon container of water set aside so that when it is time to clean/add water, it is already at room temp and de-chlorinated.

okay, that sounds good. I will check those links. until now, because the water looks really clean, I haven't really changed the water more than once a month.
i sure hope I am not endangering the fishes' lives. but it seems so far so good. I thought the filter was just doing a good job. I mean the filter gets pretty dirty when I clean it once a week, so maybe everything is okay?
but I will check the links too to see what they got...thanks!
I just changed the water in my fish tank. I took out like 75% of the water and then added some filtered water to the top.
In noticed a great deal of waste matter flurrying all around, which was probably some stuff stagnating at the bottom of the tank. I am a bit confused as to why the filter did not pick up that stuff. The filter was kinda blackish probably from all the fish poop. The stuff flurrying around when I agitated the tank water was all white as if it were fiber coverings of all the black poop.
So I wonder if it is alright and if the filter just doesn't pick up subtle waster products like that or do I need a new filter? Or should I just take out 100% of the water in order to remove all that ghost matter?
Well, I would suggest you to change the water atleast twice a month even if you use filter but you need to clean that filter regulary where all the dirt stores. Also like cleaning the gravel once a month would be fine. Your fishes will do fine.
