Fluidized bed in a wet dry filter ?

  • We are currently upgrading MFK. thanks! -neo
Good to go.

I think a big key to yours is the diffusion plate you made for the bottom. Thats the way the lifeguards are set up. I have a merlin that works okay, but doesn't have a diffusion plate and is much more finicky than the lifeguard.

Does the water level in the sump seem to have much affect on it?

The water level does not affect the fbf, the inlet for the power head that supplies the fbf is a inch lower than the return pump so that the fbf will continue even if the w/d return pump starts cavitation or pumping air.
 
Stunning Job!!! You still have it running??
 
I just took it down last week to add a drain plug under the difuser plate. I was having trouble with mts snails plugging up the holes in the difuser plate so I am adding a drain plug under the difuser plate to remove the shells as needed. Pics will be up when it is finished.

I am also designing a larger version for my 300 gl. tank
 
I am not an expert on this but I would say the sand filter has more surface area. The drawback to them though is that if not built correctly they plug up. I did not know it grew alge, it is my understanding that fluidized bed sand filters self cleans the media.
I have no exp. with the K1 media so I cant say what it is capable of.
