Backyard Aquaponics
A place to discuss aquaponics

Hello,
I am fairly new to aquaponics but gave really enjoyed and learned a lot from your posts. I have a drain and fill grow bed with a bell siphon and another vertical trickle tower system both using pea gravel as the grow media. I have noticed that people using zip tower systems use a grow media that looks similar to old fashioned air furnace filter media. I have access to new damaged air furnace filters with the old blue or white spun fiberglass filter. Is there any reason that these wouldn't work? I was thinking of cutting them into strips to stuff through a tower trickle system and growing directly in the filter media or alternately stuffing a tank full of the stuff and pumping fish water through as a biofilter. Anyone ever used thus media? Any suggestions or advice??

Thanks
Marcus

I know polyester is fish safe. I might be worried about fiberglass with your fish. Possible small pieces getting into their gills?

And a lot of the insulations people use are gonna be rockwool, but if you think about how itchy fiberglass is, how you have to wear a respirator while working with it, how difficult it is to get out of your skin.... I would worry about my fish.

I have a swamp cooler filter in one tank, it is made of shaved Aspen. I'd worry the fiberglass would break free and remain in suspension in fish tank
