To be honest, I don't think that's such a good deal. It's cheaper than buying all "new" stuff, but not not by much. Plus you are stuck with what he bought, not what you want.
That isn't a whole lot of lr
, maybe 30 lbs? They look pretty algea covered, but they can be cleaned up with no problem. As long as there is still water circulating in the tank, it will still be live.
Forget about using the live sand "as is". You can use the sand, but I would rinse the crap out of it with fw
to clean it out. It won't be live anymore, but will be safer to use.
Compact flourescent are not "high powered" lights. They are the 2nd least intense lights you can use. Normal output flourescent is the only "weaker" lighting. You would be limited to soft coral and maybe some low light LPS
Get it down to $300 and you got a deal
