Ramesh;2708243; said:I understand what John is on about but with a foam prefilter using different sizes I am sure a quick rinse of the bag is all that may be needed.
I am putting together two 55g wet/ dry sumps at the momment and wish to follow Justin Guest's advice and mix up the bio media I use in the main chamber.
I am thinking scrubbies, bio balls, sintered glass and possibly foam cubes which he thinks is under rated and recommends. I am going to throw in some Aquaclay also because I have alot at the momment.
I will post the sumps for approval because I want to use them on my new 8x4x2 monster tank.
here is what i am implying
BB grows on the bio balls in 100% pre filtered water.
old BB cell die on the bio balls and make slime from dead cells
will the slime from the dead BB wash off like in a traditional spiked bio ball or will it make a mess and required cleaning which will kill most of the living BB attached to the media ????
