paul_r Posted May 12, 2009 Report Share Posted May 12, 2009 I have put 2kg of crushed coral into my 4 footer and ph stays around 7.4, i would like to bump up the ph a bit more without chemicals so thought i could use limestone slates to make caves etc aswell. can someone tell me where i can get limestone rocks/slates etc from. I dont mind buying it if i have to. i will try mitre 10, bunnings etc at lunch but thought id check here first cheers Quote Link to comment Share on other sites More sharing options...
