GrahamC Posted October 19, 2012 Report Share Posted October 19, 2012 Had another meal last night of prawns and have all the shells sitting to be put out in the compost. But ... wonder if I can chuck a few into the tropical tank as a source of calcium etc? Quote Link to comment Share on other sites More sharing options...
David R Posted October 19, 2012 Report Share Posted October 19, 2012 You could, but there are certainly better options. Go to your local home brew supplies shop and get some calcium powder... Quote Link to comment Share on other sites More sharing options...
