some people are different, but i waited 1 full month before introducing my clean-up crew into my reef tank. i then waited another 2 weeks before i introduced my algae blenny. thats 6 weeks. probably the hardest 6 weeks of my life but i have no regrets. and aside from a lost snail here and a lost hermit there, there has been major problems yet. the bloom of algae does not necesserily mean the tank is fully cycled, but it is on it's way. i see from your other posts that you rushed along your last attempt as well as over stocked. just be patient and try not to make the same mistake twice. it's all about patience. good luck, jim.
