E-Marco 400
E-Marco 400 from Marco rocks is hands down the best stuff I have used. I got a no joke 20lb piece if shelf rock and needed to attach it to a piece of Pukani, all I did was prop it up and cement all around and it is amazing that it is all one piece now. For other large pieces, I am talking 15/20 lb pieces of Pukani, I used zip ties, and then used the cement all around... again, they are all one structure now. I don't have pics yet because the rocks are curing in giant brut trash cans, ready for installation next week after I get my tank plumbed, I will do I my best to remember to post pictures when I get them in the tank.
