Very nice. I've watched this from the first post and will be making a trip shortly to get the parts to make one.
em21701-I was planning the same setup in my head. To confirm-are you using a 3/8" or 1/4" JG fittings in the plumbing? Too much white makes it hard to tell.
One general question to all reading-Why not incorporate a 4 way T at the bottom of the chamber and run pvc to the sides of of the chamber and drill each as a spray bar to increase media contact time? May have to bump up the recirculating pump a notch. Thoughts?
