Inhibitor

System's started to create air. It's has Sentinel x100 and 200 in it and I wondered which way to go. 100?

Everything's been smoochy for a couple of years. Stuck 100 in after doing repiping (long story) and things were good, then there was kettling so I stuck a couple of x200s which, gradually, eliminated that but now, as I'm testing, I'm getting a few clumps of air circulating. Bled the rads but it doesn't seem to make much difference. It's easy for me to add any (Sentinel, as I don't like mixing) inhibitor as I have towel rails and I can drain, add, etc, just wondering whether I should be adding 100 or 200. Guessing former.

Hi, that mean a 'crap' filter like the Fernox/Spirulux one, or can I do something less involved with a water additive?
