I'm not sure what the flack is all about but I have to say from personal experience, that Mucho has been a very kind, generous, patient, and very helpful person. My father and I have been working on our reef tanks for some time. Mucho has single handedly supplied 90% of the materials (substrate and live rock) to put my father's tank together. I finally got to see the rock he got from Mucho last week and it's fabulous. Large and small pieces, teeming with life! He made the pickup convenient by meeting my dad at a location good for both of them and even gave some helpful advice on the best way to transfer the rock.
Best of all, was how he treated my mother. My poor little mom met him at a location (several miles out of his way) to pick up 60 pounds of arogonite. He kindly transferred the heavy bucket out of his car into hers and made the experience very easy for her. For that, I am especially grateful.
For anyone with doubts or bad things to say, you walk alone, my friend. Mucho is a man with integrity and an honest and helpful soul. I take personal offense to anyone who says otherwise.
