Hi Folks,
I had occasion to be poking around in my loft recently and noticed that my CH expansion tank has acquired a thick layer of porridge on the surface of the water, I suspect this might be related to when I drained the system and added inhibitor in November but should I be alarmed by this? Do I need to drain down and clean it out or can I add something to the water that will clear it?
Thanks.
I don't know what it is, but once you've scooped it out if it's fungal or bacterial a teaspoon of copper sulphate should stop it recurring.

Don't let it dry out and don't breathe it in.
I had that once when I couldn't be bothered (because it was cold up there) to tie the header tank jacket up properly. I assume that enough air can get in the gaps to sustain a small ecosystem. With the jacket securely fastened, it's been okay.
Does anyone still sell copper sulphate ?.
I think it is one of those chemicals that has been banned, in the same way that copper in brake pads is being phased out.
