today i picked up about 75lbs of LR from a Boston Reefer user, i got a good deal. The rock was in a 20 long in his basement with a light. he said it was there for a few months. he has done water changes every few weeks. i got the rock home and was looking at it when i put it into my tank( let me say this, my tank has no fish in it. Just rock from yesterday and today, the tank has not run a cycle yet.) anyway the rock is covered with little worms they are kinda pinkish red with little white hairs kinda bristles. i don't know what they are. i pulled off most of the big ones that i could see 1/2" to 2" but there are still tons of small ones left. i will try to post a pic if this helps.
