I set up a 29 gal biocube with existing live sand that my friend had in it, more live sand, a skimmer and 50 lbs of live rock. I also added a cleaner shrimp, emerald crab, and a bunch of snails and hermits. I have zoas and a few mushrooms in there and are looking ok. No fish. That was 3 weeks ago. My nitrate levels are 160ppm but my ammonia and nitrites are 0. The guy at the aquarium store said that I'm done cycling and that my sand is leaching nitrates into the water. He recommended doing a 10 gal water change and then adding nitromax marine. If that doesn't work he said to treat with AZ-NO3. Does anyone agree with this or should I remove all sand and start over with new sand?
