Best Bio filtration media?

  • We are currently upgrading MFK. thanks! -neo
I have used normal bulkhead fittings on my blue plastic 55 gallon drums and they seal fine, have also used the grey PVC (conduit) from menards with red toilet gaskets, again sealed fine. Have never tried uniseals but would be skepticle of long term use..... I'm sure they work fine but I think fittings might be cheaper, I know conduit IS.
 
Hey dude you can make some diy K1 media or you can take a large chunk of Punic stone and then break it into small balls and the stone is very easily moldable into stones or somewhat like it.
If you want it I have made a video on YouTube as 'D.I.Y Bio media's and my channel is "Aquatank boys".

i have seen people use toilet flanges as a bulkhead. has anyone tried that? it would be way cheaper than using an accuall 4in bulkhead. i havent been able to find a 4in bulkhead for under like 60 bucks.
 
With the barrels I used , I just put my pump in the bottom of the barrel, and put lava rock in mesh bags around it, so I didn't need bulkheads or to make holes in the barrel.
When media needed rinsing, I'd just pull out the mesh bags and hose it off.
Ran a PVC line off the outflow of the pump to the tanks. You can see in the photos I suspended filter socks for mechanical filtration.
I have found you can put the barrels in a different room, or even in a basement if your pump has enough head pressure.
I knew a guy who put his sump barrel on a cool basement floor, even though his tank was 1 floor up. It kept his salt water species cooler during summer heat waves.

In the photo above, the bags of bio-media are removed for rinsing, and you can see the pump sitting on the bottom of the barrel, and PVC line heading up vertically toward the tanks.
 
i think that i am gonna need to connect two barrels together to have enough room for bio media. i am going to be filtering a 3000 gallon above ground pond.
 
DeathStalker DeathStalker is cermedia worth the price? Does it actually reduce nitrates as they claim?
