Recently setup a 20g nano on saturday. I understand patience is a virtue in this hobby. I have approx 10-15lbs of base rock and 5lbs of live rock. Used Aragonite live sand.Yesterday, 3 days after initial setup up i added 1 piece of raw shrimp into a media bag in hopes of decaying and building up bacteria to start my cycle. How often should i be testing my parameters? Once i see ammonia spike is that when i pull it out?
