Aquascaping concrete mortar

[Richard_Dicosimo]

Hey guys, I'm planning a new system and I want to do something special with the aquascaping. Through my research I came across a product called marco e400.

It appears to be a reef safe hydraulic cement. I know that there are a couple manufacturers who make similar products but this one comes in a volume close to what I think I will need.

Anyone have any experience with a product like this?
Anyone know where to buy it?

Thanks guys
