once my tank is fully cycled in a month or so i plan to add a rbta and a black clownfish as its first inhabitants other than the clean up crew. my question is threefold, first is 216w of t5 lighting enough? secondly once i get it do i just place it on my live rock and then let it pick the place it wants? lastly i have 2900gph of turnover, that should be enough flow for almost any coral in a 72g right?
