DIY Cheap Bio-Filter for Aquarium

Hey everyone :) I wanted to make a cheap bio-filter for my recently made aquaponics system.

Since im using a flood and drain table I took a 3 inch net pot and cut out the center and place it through the drain hole. :)

I bought some cheap scrub pads from the dollar store and cut out a piece for the bottom of the net pot and cut a hole to put the drain hole through. I then place two scrub pads around the sides of the pot. Easy! :)

I went to the pet store and bought some activated charcoal. This box will last a while i could change the fiter at least 5 times.I added a facet screen with a grommet around it to hold it tight against the drain hole and to protect it from clogging with charcoal. I filled the bottom half of the filter with just activated charcoal, and then mixed some hydroton, gravel and charcoal together for the top half of the drain.

And there we have it, my timer runs for 5 minutes to fill the flood table and then the filter takes it time to clean the water and return it back to the tank! :)
