Hey everyone, I'm dealing with a some very stubborn hard water stains/ lime on my empty 80g, ive tried the vinegar circulation method and lemon juice so far but it hasnt come off in the slightest. any tips and/or tricks I'm missing?
will post photos of the tank when I get home
 
I've experienced similar, and if it's what I'm thinking, nothing seems to take that white film off an older tank. It's like it's in the glass and no amount of acid or scrubbing seems to put a dent in it, at least for me. The only good news is that it's a lot less noticeable when the tank is filled.

You'll can try citric acid. I've never had to deal with water spots like that but it seems to work on everything else I've tried

I'd agree with @Fish Fan in that it seems unable to remove at all with all I've tried including citric acid. I tried for months and it's a waste of time and expense.

When filled they blend in and are unnoticed with water agitation and what not because your eyes are never drawn to them.

I can live with them when full and I do think that your wasting time and money trying to remove them after what you've already done.

Even imported(for me) Barkeepers friend ne er touched it even after soaking for days and scrubbing so hard I thought I may damage the glass so gave up.

that unfortunately sounds a lot like what I have, its above where the water hits so if I cant knock it out with citric acid I'm going to just put a strip of black tape or some kind of coverup
