Aquarium Glass Issue

I’m having a hard time finding a way to clear aquarium glass for a 120 gallon high I purchased.

I’ve tried vinegar, bar keepers friend, rubbing compund. Nothing’s has worked. I’m probably way off, so I’m hoping for some ideas?

 

I was having trouble with one of my used tanks too. And I went and bought a skinny green scour pad and used that with the vinegar and it took care of it!! That little green pad worked wonders! And my tank looked very similar to yours. The vinegar did NOT work when using other scrubbing materials. But the scour pad and vinegar combined was excellent!

Here's a link to an example

 

If its adhesive have you tried acetone or nail polish remover?

 

It seems almost like a condensation inside of the glass. I will try the skinny green pad. Trying anything about now.

 

is it dried up algae? I've had that before. I used a pot scrubber thing. Took it right off

Let me know how it works! I was pleasantly surprised. In fact, a scour pad wasn't really what I was looking for, but the store I went to only had them and no other kinds of sponges. Thank god that's what they had though! Because it worked wonders!

Seriously, my tank looked just like yours! So I am feeling good that it will work for you!

 

I have a magic trick for you: muriatic acid will melt off lime deposits. That stuff is like a super, super strong vinegar, so with ample rinsing it will be just as safe for your fish as using vinegar is. Heads up, it will destroy your clothes so wear protective clothing and gloves (if using plastic, do a test first to see how the gloves hold up, otherwise use gardening gloves and rinse them a lot as you work). If you do it indoors, make sure you wear a mask because it produces nasty vapors. I would recommend doing it outdoors and keeping a hose handy to rinse the stuff as you go, but you can also put the tank in your bathtub and work with the shower turned on. Just wear a mask, close the door and make sure the fan is on. It sounds like a lot of work, but you don't actually need to scrub anything so it's over quickly, and the aquarium will look like new afterwards.

 

Still have the same issue. This is after the muriatic acid. I’ve tried rubbing compund and just about everything else I can find

 

These spots where the suction cups were are clear so it makes me think this is something that can come off.

 

Did you try the scour pad with the vinegar?

 

Since muriatic acid didn't work, you're not dealing with lime deposits. Any chance it could be an adhesive?

 

The water where I live is murder on glass tanks. Actually etches the glass over time, to the point where cloudiness like this is permanent. I have tried everything including buffing compounds with no success. If whatever it is doesn't come off with a razor blade, it's not going to. It absolutely sucks.

 

I have a 30 tall that was given to me that looked exactly like that and I had the same problem, and tried all the above. Eventually I used bar keepers and 1000 and 1200 grit automotive sand paper, it looked a little better but not much, it was so bad I could not really use it for a display tank but using it for a breeder it really didn't matter.

 

Barkeepers friend worked really well for me. Just rinse a lot after.
