I started my new tank with just regular dry reef sand from the pet store, and my tank is at the end of it's cycle. Is it to late to remove the sand and go with some live Aragonite sand? I don't want to have to repeat this cycle over again because i'm ready to start adding fish. I want to switch because when i went to do a 10% water change, i kept vacuuming up all the sand from the tank when i only wanted to remove the waste from my CUC. I'm thinking the aragonite won't come up as easily as the sand. So can this be done with out having to repeat a cycle??
