Hi Friends !
Just wanted to request for some advice.
In my Freshwater Aquarium's top filter (the one on the Tank Cover), the water is drawn from the tank and poured in to the 2 compartments where my Fish dealer has placed the material in the following order (exactly as in the order) -
Water - poured in (drawn from the power-head)
----------------------------------------------
A layer of Filtering Sponge
----------------------------------------------
A layer of Activated carbon in one compartment and a layer of some ceramic barrels in the other compartment
-------------------------------------------------
A layer of Filtering Sponge
------------------------------------------------------
Water poured in to the tank (passing thru all of the above layers)
Now, he says that I need to add a layer of some Bio-Balls (small black colored balls) on top of the above setup and then a layer of sponge above that. (on top-most)
I really have no idea on what are these Bio-Balls and if they are necessary ? Kindly advice and help me friends !
Regards
Kush
