Additional Notes For Construction of the DIY Carbon Tube Filtration System
Challenge: Can't get ASB tube material, or feel thin wall PVC
will work just a well, or better?
Solution: Go ahead and use PVC, it's lighter and cheaper.
Challenge: After washing and "fizzing off" the carbon there
still may be some black/gray residue coming out
of the tubes.
Solution:
Take a garden hose (do this outside) and let the
water flush through the tubes to help remove any
residue. This also allows to test for leaks.
Challenge: Don't have the right size "tap" for the male
hose
fitting hole in the end cap?
Solution: Use
a regular drill bit, stick connectors into snug holes
and use JB Weld around the outside of holes and
connectors to secure and seal. Let dry and cure over-
night.
Challenge: End caps leak using teflon tape?
Solution:
Glue on all end caps.
Challenge: After gluing end caps on, still get some leakage?
Solution:
Dab more PVC glue around outside seam of end
caps.
Challenge: Fish appear stressed for oxygen?
Solution:
Add a couple of airstones to help with
vertical water movement in tank and aid
in the oxygen/carbon dioxide gas exchange
that takes place on the water surface.
Challenge: Magnum filters the water well, but need more
circulation and water movement in tank.
Solution:
Mount a powerhead (or two) on opposite end of
tank from where the carbon tube outflow returns.
