Do both... put the refugium before the pellet reactor. that way there is nutrients for the algaes (from the nutrient rich return tank water)... then run it through a biopellet reactor and aim the return from the reactor to the intake of the skimmer. DONE!
This way you will have some chaeto/caulerpa and all the critters that are good - not practical to export all the nutrients this way but a few. Use the Pellet reactor to get rid of the bulk of the nutrients... probably leaving a bit of PO4 and then in the last chamber run a small pump 300 gph through a TLF150 with Rowa (just gate it back for the right flow)..... your return water (to the tank) should be very clean....
Start with 1/2 of what is recommended for the biopellets and see what happens to your nutrient levels (give it a few weeks for bacteria to grow).... remember that some NO3 and PO4 is not bad.... I keep my NO3 @ < 10 (average 5) and my PO4 at <.1
I am using this method... everything is happy and I dont need to fuss with dosing anything.... super easy and simple - reactor is always running. Bacteria grows & dies off of the pellets as nutrients allow, it is like a shock absorber.... and you don't need to mess with it.... it just runs - with vodka and sugar you are always messing with the dosing and it can be a PITA...
Just my opinion....
