Denigrating media in reactors

[Rmckoy]

I have 2 phosban reactors I am thinking of building a diy reactor
Essentially . Either sulphur or other nitrate removing media with very slow flow ..

One with nitrate remover in line with another with a phosphate remover ( rowaphos ) ?

 

[Rmckoy]

found this video which explains exactly what I was thinking of .
but if I put sulphur in one .
and carx or another media in the other .
2 questions
Will the phosban reactors be enough for a 230 gal ?

to run them in line ( from one to the other )
Is just a few drops out of the second enough ?

what media should be first ?

I wouldn't underestimate how good sulfur reactors remove nitrate over time. That alone can clean it out. I wouldn't do the phos reactor in line with it. My thoughts are mainly that A: it is not enough flow B: could cause some weird reactions in the process.
