Hey all. I actually was a member years ago, back when this was an arm of Reef Central (2006; 2008??). Went to a few of the meetings at the zoo and that was ALWAYS a good time!! Anyway, I fell out of favor with an RC mod who made it difficult to be engaged in the hobby as a nube running a new, first time SW tank. After a while, I made some mistakes and things started dying. Unable to figure out what went wrong and busy trying to keep up with life while starting a new business, the tank basically became a 75 gallon rectangle of saltwater. It was shut down and just sat for a long time, then most of the water was removed except what covered the sand bed. Fast forward a few years... So here's where I am today: I have a 90G tank and a 30G sump I purchased from a member back in '08. Along the way, I collected a CPR fuge light, an ASM G-3 skimmer; a Mag 18 and a Pondmaster Mag 15 pumps. I have boxes of items I bought but never used. I am 'preparing' to relaunch a new tank in the not too distant future and have some specific questions: 1. I have all the former live rock which was put in a covered plastic garbage can and has been inside the house (room temp) for a few years now. Obviously, it is very dry and assumed dead. Do I need to give it a bleach or vinegar bath and rinse, or is O.K. to use as is? 2. I have all the sand in another covered garbage can. It was wet when put in there and is still quite wet today as it has about an inch of water on top of it. Can it be cleaned and reused? If so, how? I intend to set the tank up and let it cycle for months, if needed before adding anything of note. Thanks in advance for all the advice/help I can get!!
