Hi. I am a new to the hobby just set up 29 gallon tank about a 3 weeks ago. Started with live sand and live rock that was already established from the lfs. I am running it with a tom rapids pro3 filtration system and two power heads for circulation and have ocean current lighting system. My question is about the cycle. How do u know for sure if it has cycled. all my parameters are where they should be according to what i have read on r2r and saltwater aquarium for dummies.
