dirty glass need help
 

I bought a used 90g tank, and the inside of the glass is covered in a white film :frown: I tried scraping it off withe a razor blade and that didn't do anything. Anyone have any suggestions.....
Thanks

You can try C.L.R. with a scrub pad,but make sure you rinse real good a couple of times with hot water.

Use full strength vinegar.

Full strength vinger didn't work. Going to Rona to get CLR

bleach works really good just be sure to rinse really good and use lots of de-chlorinator

You may have to let the vinegar soak a bit on the glass. Try soaking some rags in vinegar and placing them on the glass. Let sit for 1/2 hour, should come right off.

CLR didn't work either. I'm filling the tank now to see if it is noticable when full. I would imagine that it is just a calcium build up seeing as how it was a reef tank before. It has been down for about a month now. So I'm hoping it is not going to be noticable.

My favorite hobby is wine making. You can get a glass cleaner that seems to work very well (at any wine kit shop). One would fill the tank with hot water, leave it overnight, and almost everything comes off (everything that can grow in a wine bottle). I have tried it on tanks also and it seems to work. It is also very cheap...

:confused: is it on all sides or is the front clean?if just on the ends and back,maybe just clean as much as you can and leave as is?

It seems to be on the front only. I don't know if that was because there was algae on side and back or what. It isn't noticable when the tank is full. I would like to get rid of it though. I'll try the wine bottle cleaner. I alway considered myself as a wine bottle cleaner :smile:
Thanks everyone
