That means he broke it down before the move and reassembled once at your house you will still have a small cycle even if he did everything right, had he ever moved a tank before? Did he use new sand or rinse the old? How mucb of the old water did he use?
You guys need a test kit for yourselves and save the trip to petco, they use the strips and those are useless, you need a marine/reef specific test kit, I suggest the API master kit.
What equipment is he running on the tank? Hob
? Wet dry Sump? Refugium sump? Canister filter?
