Anyone else struggle with this product? I used it a few years ago, fixating the aquascape in a Red Sea Reefer XL 300 that recently split in the seam. I'm in the process of setting up a new tank with CaribSea Life Rock, but I find the Stonefix to be rather crumbly, even after 24 hours. I've experimented a bit with the water:Stonefix ratio, but I'm still not confident about the longevity of the finished scape
