Welcome to the forums poolog

If the "stain" is grey it is probably not related to the ionizer. Is there any chance of a photograph?

Waterline discoloration is often due to oil, swimmer residue or scale. Can the stain be removed at all with a light abrasive (e.g. Scotch Brite)?

Increasing the pH and TA makes the water more prone to scaling. Do you know the calcium hardness or total hardness value for your pool?

Hi Larry,
Thanks for the quick response.
I had assumed that it would be the ioniser as I had no problem when it was a salt pool.
It makes sense that it could be down to calcium as the hydrochloric acid removes it so quickly.
I will get it tested and get back to you with the results.
