So I have a cyano outbreak that just showed up over night exclusively in my fuge in the sump. My parameters are all within normal range and it’s a 2 year old tank. The DT is 80 gallons and the sump is 20. I was thinking of pulling my live rock and chateo out and putting it in a bucket while I pull the sump out and do a massive clean to the sump. I am concerned for sure about potentially “shocking” my system. What are your thoughts?
IF you do, please start a build thread. (I don't have one yet but I'm working on that too. )
