Best source for chemical/pest free base rock? Reefcleaners? MarcoRocks? ????I'm sure this topic has been beat to death but since I'm new and need a lot of rock (just set up a 210gal) what is the best place to buy pest free and chemical free (no phosphates/silica/etc)?I have heard very good things about ReefCleaners and MarcoRocks; how would you rate their stuff?I have heard pukani gets you a lot of rock for the money but that they leach phosphates unless you treat them for weeks which I don't want to do...Suggestions? Thoughts?Sent by Samsung Galaxy Note 2 and Tapatalk 2
