Hi! I'm planning on getting a bi-mac in the next couple of months (still cycling the tank) and had two questions abou them. 1. I add a Kalkwasser (calcium) powder to my reef tank for the inverts in there (crabs and shrimp) is this somthing I should do for the bi-mac (or anyother additives/trace elements?) and 2. I have a ton of calurepa in my reef tank is there any benefit in adding this to my octo tank or will it do any damage to it?
