Hello guys... I'm new to SW and my fist tank have been up and running for five weeks now and I have not seen the cycle yet... Can someone please let me know what is the time frame will the cycle starts... basically, I have not done any water changes since....all I did was adding fresh water to replenish the water from evaporations, and maybe 20 minutes cleaning per week.... I don't know what to expect next... my fish are happy, corals are growing...I was thinking if nothing wrong then I don't have to worry about it......However, after reading some of the articles on here that makes me start to worry of what will happen next...I'm not sure if I need to do the water changes or not..... I have brought one week old water to the store to tested out (a month ago) and was told just to add some reef builder and that's all I did.... Any advices will be appreciated
