I'm not sure on the base rock j&l sells but eli from fijiji reef rock has some nice pukani rock. I purchased from him about a month ago about 74 lbs I gave it a bleach bath and meta tic acid bath and put in tank then I purchased 60lbs live Fiji rock that had lots of coralaian alga on and being new to the hobbie was worth it checking out all the critters living in it and new growth coral on the rocks. And I think by doing that I never really seen a tank cycle but I let it run with nothing in it for a couple weeks. I have had fish and coral in tank for about a week now. I have hair alga on the dry pukani rock that the fish love eating and the Fiji rock is building more corelane
