I ran out of polygenic. It to high to buy more. Instead of using quick set cement
Ill wait for it to cure and seal it with clear coat fish safe epoxy from polygem
One is a lettuce coral and the other is a antler coral (elkhorn coral)
I'm gonna make about 6 or 7 elkhorns and tie them in together at the base with more cement and big one big elkhorn for the center of my 300 gallon
Concrete didn't work. Too thin of a coating. This one was done by insulation foam. Ill covering in epoxy and attack it in a heavy piece of DIY concrete rock so it won't float
