Only concern is choking if too dense, got to replace or wash freq. Must watch out.

Agree with itchy. The only concern is that this kinda sponge is very dense and may result in choking and water may not pass through easily.

I seconded or agreed with Bro Itchy feedback on its density. You can tried but have to closely monitor to avoid any flood of your sump tank, bro.

Maybe can be used to scrub the tank glass like the melamine foam?

Let's get back to basic. The most important part of the filter is the medium. This is where the bacteria should do their work. That is why we need to provide them with a material they can colonize and which is in a permanent flow of the water that needs filtering. Large numbers of bacteria are required, which means that we need a large surface area in the filter medium. This can be achieved by selecting a material that has many holes and capillary pores. These will increase the total surface area for a given volume of filter material.
The size of these holes and pores should not be too small, because the bacteria would otherwise block them or even wouldn't fit in at all - we're talking microscopic organism here... When holes and pores are so small that bacteria do not fit in anymore, only the outer surface remains to be colonized by them. In a nutshell, IMO for sponge to work, pore sizing is essential or else prepare to mop the floor.... |
