phosban reactor

i am looking to add a phosban reactor to my system and had a couple questions. i have decided to get 2 reactors one for GFO and the other is still in the air any suggestions welcome. my next question is if i put the two reacotors in line with each other can i add a UV sterilizer in line with them if so where in line and second what pump should i go with?
ia m going to go with the TLF Phosban reactors and for pump options the have pump options you can pick wich include: Cobalt MJ600, 320 (Seltz L30), and Eheim 1250 hobby.

i have a 40 gal display tank w/ 20 gal sump. fuge in sump also coralife protein skimmer. multiple fish but manly coral tank.

 

I have a TLF's and it's a bit of a pain to disconnect to clean, imo. I haven't used Bulk Reef's version, but it seems to be easier to disconnect.

 

i would agree but with bulk reef supply's it does not seem to stable as a stand alone and should be mounted to something. that would the only reasoning i would not choose it but i do like the option that comes with a in-line double.
