So, how does one remove old dead coralline or calcium build up on the inside of a tank? There are white semi-transparent circles all over the inside of our tank that we want to get rid of. Any input?
We actually have been considering just what you said criagar, and getting a few gallons of vinegar and filling up the tank. We will need to get the tank plumbed before we can do that though.
If you can , turn the tank on its side, takes less vinegar. You have to let it sit to really get it to work. When your done, place the tank on another side. 4times should do the trick. Then a little scraping.
Haha hey Drew, you wanna come help me turn the tank on its side? Lol, after watching them lift it I'll just spring for the extra vinegar and not try to move it ever till we move out of here.
