so who wanted some kalk?

[Dorkel Marine 1]

Definetly would like to search for bristle worms. Could you briefly explain the use for kalk. I read a little about it. But I am in the process of rethinking my whole approach. Will start to use additives. But i want to be careful. But a lot of tank pictures talk about using Kalk. Oh. Thanks for the reply to my sob story. Appreciate it. Until I'm real confident in my water quality I'll take you up on the offer. Thanks again. Maybe you could reccomend a good small skimmer that hangs on the back of a tank.
