cool you have the black sand too huh? i had that in my octo tank i would like to use it in reef set up too........................ but isnt the arragonite supposed to help with the ph balance? or can i just overcome that issue with regular water changes?

[JeromeBaker]

are there any reef enviroments in the ocean that naturally have the black sand? Either way it looks awesome.
