If you look at the the posts and there are a lot. It appears that the sulphur media to use is from Midwest (its (1) preseeded (2) hard) available from them and I think one other place. They are also using aragonite with the sulphur in the reactors.
There are some that were made w/ PCV, others with Phosban reactors, other from scratch. The best choice to me is an clear tube to so you can see when to change the media.
It appears that the water is passed throught the aragonite not to dissolve it, but to reduce the Acidic not an alk/calc drip. And you do not put the output water back into the tank until after its broken in. The output water will have very high NO2, both the NO2 and the NO3 need to be zero before the output goes into the tank.
