Under gravel filter enough


Rhamp

Recommended Posts

Has anyone tried a reverse underground filter?

Power head to push water to underside of gravel, then up through gravel.....waste then gets trapped under the bottom of the gravel

Each time you do a water change connect to U/G filter inlet and water is drawn through gravel from top to bottom 

Trapped waste is then removed....

This is opposite to normal U/G filter but saves gravel vac???

This helps, but if speed of cleaning and mulm removal is the result desired then air powered sponge filters are way easier and more effective. Its only the aesthetics that UGF has the advantage in. Although when you use a powerhead on a UGF the aesthetics take a huge hit anyway. Also,if the idea is to blow mulm around rather than suck it into gravel.....  water clarity takes a hit too.
