I have a cyano outbreak and I started my tank with dry rock if I decided too switch too tampa bay ocean live rock but just rock no sand will the cyano that is still on my sandbed just colonize my newly live rock and just take over again or will it die off? And if I decide too add tb ocean live rock should I remove all cyano from my back chambers and pumps or will the new live rock with all the biodiversity wipe it out on it's own sorry so long just wanna be sure it is worth the money because it is pretty expensive any help greatly appreciated thanks
