Those look just awesome!
Both Petco and Petsmart have the dry Aragonite sand. Just ask them.Well I just picked up a 20 long for them! I will try to do a journal on it! My LPS (went to 3 diff ones) don't have the Aragonite Sand. They only have a Ciclid Substrate, but it had copper in the ingredients, so I am not sure if that will work. They did have Crushed Coral, but only in white. I was really hoping for a black substrate. Is there anywhere I can get it online? All I am finding is the stuff with the live bacteria for saltwater tanks.
Worst case maybe I could use Crushed Coral under regular black sand or maybe in a media bag in the filter, then some Seiryu Stones? Also what plants can I use with such a high pH? Mosses and Java Ferns? I was hoping to do some floaters too if possible.
