Tbh, I'm not 100% sure about this but i heard that bagged live sand with the exception of oceans direct really doesn't do much...I've even heard a few times from different sources that the bacteria in most bagged live sand is actually freshwater bacteria which won't help a reef tanks biodiversity. If you wanted to get some TBS sand from the Gulf that would definitely help. Honestly I'm a fan of live rock fresh from the ocean which is more biodiverse than you could possibly imagine. Where i am it's easy to source from the ocean but I'd imagine where you are your best bet is maricultured live rock which is also great from what I hear.I added caribsea arag alive fiji pink sands. Will this add any biodiversity at all?
