Looking for opinions on marinepure. I’m in the process of setting up a new sump on my current build and can’t decide if I want to go with the cubes or block in the fuge. When I bought the tank the guy gave me a huge block of it that he had in his sump (freshwater setup) and it seems really brittle, I don’t know how long it had been in there but the thing will crumble in your fingers if you mess with it. Is that common with the block?
