how well will this filter work ?

okay so a 400 gph sump pump buried in gravel in a tub (beta tank ) with java moss growing on it so the pump pulls water thru the java moss then into the gravel then out thru a hose to the other side of the tank
like this

 

If the java moss doesn't get clogged, eventually dying, I don't see why it shoudn't work.
The problem I antecipate is the java moss getting filled up with detritus. You should get net to prefilter and perhaps a coarse spongelike 'ting' to take the load off the java moss.

And don't forget the moss nedds light to live, so you'll have to iluminate your filter...

 

would it be effective filter for a 55 g ?

 

Yes, if you keep the moss alive...

 

its inside the tank under high lighting so it should be okay

 

hmm I'm just running this so hopefully it goes well

 

You have clean water?
Or a prefilter (grid or net) in front of the moss?

 

the water is clear and the moss dosent appear to be clogging

 

the water is clear and the moss dosent appear to be clogging

that is just one day in operation, wait a couple of weeks and let us know

 

3 days running so far

 

Yea, I'm sort of curious, too.
It is undoubtedly a new way of filtering

 

its more or less I high powered ugf will keep track of how it goes
