well... i am looking to make a fuge out of a large aquaclear HOB filter... remove all of their filter media and create some sort of fuge on my own...
the thing is... the standard way that the water moves through the filter is up from the bottom... so putting sand in there is not very practical, if not impossible... so... would a coulple small lr frags supply an area for macro algae to grow???? this way, the water can still flow from the bottom, up to the top and back into the tank...
