I wouldn't buy live rock unless you see what you are getting. I would want to see the shapes and pick them out to create a cool aquascape...plus you are spending a lot of money...you deserve to be picky!
Well I was thinking of buying a 50 pound box and would mostly be using it to cycle a 75 gal. tank and as base rock,not to mention would be alot cheaper than the lfs ,it is $6.99lb there and have to drive a hour for that,so was kinda hoping someone had bought from a ebay dealer or maybe even knows a reasonable online store,kinda on a short budget ,since I have two rug rats and a wife that takes care of most extra cash I get,lol
yes i bought live rock off ebay and was very satisfied. i don't believe the seller is still active but i think the rock is still sold on ebay through other sellers. it's the cured figi that works out to be $2.25 or so a pound. not quite as nice as what i can get at the lfs but that stuff is $7.99 so it was sooo worth it to me to buy off ebay.
Oh well if it is that far away and you are not a regular or whatever then ya i guess you can opt for the cheaper route for sure and just make it work with what you've got. I bargained the price of my rocks down and since then I have become a very regular customer with them but it seems like your situation is much different. Get some online and let us know how it goes and take pictures of course too!
