Hi, can anyone tell me is Fernox F3 inhibited while its left in the system for 7days in other words is the system rusting while it is in?. Also since the cleaners been in the vent over the fe tank has been venting a little surge of water on pump speed 2 only each time the pump is turned off...

Looking at the safety data sheet X200 contains Potassium hydroxide which acts as a water softener hence it breaks down the limescale over time making it soluble in water. Clever bit of water chemistry.
