Hi, don't know if you still need any rock but I purchased the 40lbs of nature's ocean base rock on amazon. It was a little over $60 with tax. I ended up with 2 huge shelf like pieces and 1 a little bigger than a softball. I still have the 2 huge pcs. if you're interested. Sorry I can't do any trading but would take $40 for the 2 rocks. Thanks.
Id never trade for rock you never know what your getting unless its brand new. Id sell the skimmer and buy new dry rock from a vendor. This has cost me in the past. Just my advice. All the best !!
Thanks for the advice but I've always bought or traded for used rock. I always give it an acid bath and bleach bath and it sits for a couple of months. Just have to go thru the process
