There are hard water spots (I think) around the top of my acrylic tank. It goes away when wet but comes right back when it dries. I tried just scrubbing it off but that didn't work. Is there any way to get the spots off? Thanks in advance.
 
Try vinegar & hot water .... although I find that eventually hard water permanently etch glass & acrylics so there is always a fine white film which disappear when wet (but comes back when dry.)
 
Alrighty. Thanks I will try that. As long as the water is at that level you won't be able to tell it's there, I guess.
 
I am a saltie and once the SW goes in, I can scrape it off with a razor. I do have well water and the white vinegar will clean it off, if soaked long enough.
 
I wouldnt use a razor on acrylic. I use the water and vinegar method as well as using undissolved salt and a wrag or paper towel to scrub the spots with. Since I have never had an acrylic tank I don't know if this method will scratch it or not.
 
Agreed, don't use a metal scraper on an acrylic tank!
