I have a filter system. the water flows into a small tank, with a several partition in it and is pumped back to the tank again .. What does this type of filter system called ?
Second, what would be the ideal substance to be placed in those partitions in sequence?
Water in ---------------------> water out
Sponges ---> carbon ----> bioballs ?
What's the use of bioballs ? to me , they just seem to be small rubber balls ...?
thanks
