Carbon Filtration

[hillegom]

The carbon we use is in small grains or pebbles if you will. the HD carbon is probably one big extruded block. Ten micron you said.
So in our filters, smaller particles will go right through the carbon filter with a low pressure pump.
In a 10 micron carbon block these particles will plug the filter quite quickly.
You would never get the water volume through the block that they are designed to be used for. As well they are designed to be used with house pressure water so you would need a high pressure pump.
Good idea, but I would not use the HD carbon block in the aquarium. As also stated already, we don't know the quality of the carbon.
