Just dropped 2 cocktail shrimp in my 75g tank with new marco rocks and new saltwater to start the cycle process. I know I need to keep a check on ammonia, nitrite and nitrate levels, what other levels do I need to keep an eye on? When do I need to start looking for spikes? Running lights from 6pm to 10pm, 4 hrs a day, to start and skimmer off, is this the correct procedure? Thanks.
