Oh Okay I will let it do is thing for a few more days....you used all dry rock? You think the sand will help start things up?I did have a similar situation with mine. But it looked like it had been on the shelf at my LFSfor awhile. It wasn't out of datebook they keep the store over 80 degrees year round and I'm sure it had been shipped in the summer. But I think I gave it 5 days and added some Bio-spora and things started working. Idk if it took awhile to kick in or if the Buo-spora helped but it didn't hurt it.
