I recommend buying a glass carboy for secondary. I guess you could use a plastic bucket, glass is preferred. Then you can see the yeast and other stuff settle out and clear. Do your primarys have spigots on them? I ask because if they dont and you rack to a bottling bucket, you rack to secondary the same way. You may just be using the spigots to transfer though.
Anyways, buy a racking cane, or you could just use siphon hose, but a canes easier IMO. Youll need about 6 ' of hose. Sanitize EVERYTHING first. Put the racking cane in the primary, fill the hose with sanitizing solution, hook it to the racking cane, let the hose down into a bowl or something and let it go for a second until its all beer coming out, pinch it and then stick it into the secondary and it will fill it up. Hope tha thelps.
