Well I'd like to redo my aquascaping and remove some live rock in my 30g Finnex, but Im wondering if it will induce a new cycle? Total water volume is 25g or so, and I have tons of live rock (moved from my 55g), that I'd put at 45lbs or so. Its cramped and Im worried that the dense rock mass is trapping detritus, and that not lots of flow is going around. Any thoughs?
