krellious Posted February 23, 2013 Share Posted February 23, 2013 pressure washer, boil in a large pot and scrub or rinse underwater hot water and scrub with a toilet brush. Or i think you can bleach it but not sure of the bleach to water ratio needed Link to comment Share on other sites More sharing options...
spedwards Posted February 23, 2013 Share Posted February 23, 2013 You may find the limestone raises the pH of the water beyond the comfort zone for oscars. Link to comment Share on other sites More sharing options...
Ged Posted February 23, 2013 Share Posted February 23, 2013 High pressure cleaner will do the trixk.The limestone will not only raise the pH of your tank but will also affect the hardness of the water. Oscars will tolerate a range of water conditions but tend to do better with a lower pH and softer water than I feel will result from the addition of the limestone.
