One of the earlier posts mentioned that if I use dry rock then I will need to boost the bacteria and ammonia in the water. Any tips on how to do that or did I just need to worry about that after I rebuild the base of my tank? LoLThat sounds like it. It does depending on how deep you want the sand bed. I like about 2 inches. It is possible to go without or have to or 6 inches. I think 1 or 2 inches is great
