Aragonite or sand?

[divemasterjim]

I currently have aragonite as substrate, it has been in there for about 2 years.
I only fish and live rock in my tank and want to get a bunch of corals. Should I switch to sand?

Sand does catch less debris. As long as your NO3 is staying low with your current substrate then it is just a personal preference. ( I use sand)
