Hello,
Whilst browsing the old posts, I found some people recommending the magnaclean filter and others saying they were a waste of time and you should treat the cause not the symptom. What is the consensus now? Are they worth having? Are they just a magnet that the sludge sticks to? What is the bets price for one? Despite having Fernox inhibitor in my system, I did find some black in the water I drained when removing a radiator for decorating recently.
Thanks.
