I think I like them both, the stores for the once in awhile latest product, sometimes knowledgeable staff, and things such as salt and fish.
This board has all the info a reefer needs, sometimes friendly people
all the trades and purchases of coral, fish, and used equipment.
and just for the record I'm not saying don't use kalk, you just have to be careful with it outside and inside the tank. I have switched like many others have either to upgrade to reactors, two part regiments, dossers and such. I actually dose a homemade mix of baked baking soda and bulk calcium chloride(thanks to a link off of canreef) and prefer that over some overpriced name brand mix.
Reef On All!
