ok..So I have decided to go to freshwater, seeded, my personality requires constant challenge..I have a few questions. I will empty the tank of all my salt water "stuff"....(to some fortunate reefer yet to be determined) Now, what to keep... skimmer? I will still use the sump / return / fuge...what goes in place of the cheato? I will still use carbon reactor? Is ro/di still required? how about lights..T5's ..what bulbs are good? can I still use the purple plus/blue plus etc? Temperature? about the same? Just rinse everything good before I begin to add wood sand rocks? I know its a bunch of questions..I am again a Newbie...a new adventure..just trying to get a handle on where to start...I have been reading around the forums and some other articles, but I know this is where I will get the direct answers I require. Thanx folks..
