i cant clean this film off my glass help please.

what about CLR? it would get rid of the calcium build up? you would have to really really clean the tank out well though

 

I have no idea what's in CLR, so I'd be hesitant unless this is common practice that I'm not aware of? If it's calcium, vinager should work, but it's a weak acid, so it can take a long time. I would try a razorblade first, then maybe clean it up with vinegar.

 

no Its not I was just brain storming ;D

 

It's used to what to the glass? I didn't know... well, actually I had a 10 gallon with water and a good amount of muriatic acid to dip my pumps and clean them for well over 6 months and the tank cleaned just fine without any visible damage to the glass. Hope I did not weakened it any!

In my limited experience, a razor blade used properly will remove ANY deposit on glass, irrespective of what it is. I've seen a few key questions asked that would require answers to help. The one that sticks in my mind is, "How old is the tank? was it scrubbed too aggressively or too abrassively and it is scuffed maybe?"

If it's physical damage, i.e. abrasion, then you're unfortunately out of luck--however, that's unlikely unless the tank was in this condition before filling.

CLR is a chemical used to rid surfaces of lime and scale. It's safe on glass providing you thoroughly clean glass after application.

When you said you tried vinegar, I'm assuming you did so on a dry tank. Chemicals must be used on dry surfaces.

Good luck!

 

Your right Magnus... Sorry about that, muriatic acid is actually just 10% hydrochloric acid, which will not etch glass.... You could actually use it. Sorry SushiGirl

 

Direct from the OP:

 

If razor blades aren't working, then I wonder if ReefSparky is onto something and the glass is damaged. Did anything come off at all with the razor blade?

 

Most people I know use muriatic acid to clean tanks. That's what we used to clean that really messy 140 that's sitting in the garage.

I was going to recommend CLR, but since I don't know what's in it either, I didn't. Glad someone else knew that if you rinse it very well it'll be fine.

 

I have an idea. Mix windex, bleach, vinegar, muratic acid and razor blades. Place in blender.
