Why not fed from the overflow?
To your question, I personally like BB w/LR and cheato mainly as easy to siphon detritus (but then my fuge is tied to a drain) and to get any shedding from the macro. I don't bother with a DSB or Phosban as test get 0 or near zero Nitrate (Salifert) and same for Phosphate (Lamotte).
