So this is once again about the 29g tank I was given. I love it (keep changing my ideas on what I want in it! I am now thinking maybe a gourami and a little school of rasboras as well as some corycats...Or a sorority of betta girls with the harlequin rasboras, corys and a few kuhli loaches... Then I just saw a picture of an African Butterfly fish and thought it was the coolest thing ever, but don't know if they can be in a community or not...decisions, decisions!)
Anyways, the whole point of this post before I got sidetracked, is about the actual tank. My boss admitted she was a horrible tank cleaner and would let her 4 goldfish sit in the tank until you could barely see them.
The tank has a horrible white film around the top where the water level was at, as well as all over the filter and the hood where the light shines through. I have scrubbed and scrubbed and scrubbed. I have rinsed, I have used vinegar, I have tried using a razor blade to scrape off the white stuff. Is it lime? Or from hard water? Is there anyway to get rid of it, or am I doomed to a icky looking tank? Are there any safe chemicals I can use to get the white film off? (I know I shouldn't complain because it was a free tank, but still) Thanks!
