yeah, definitly not dosing without testing! Learned that with the iodine too. (It sits in the closet now.) Well, how does a 5 gal. water change every other week sound (in a 55)? I want to devote this tank to corals and just a few fish. You have to have proper levels of magnesium for tha inhabs. to use calcium right? So if my calcium is being depleted and the corals are growing, then I'm okay. I've gotta go read some more........
Thomas712- thanks for the input on my fish yesterday, sadly he is gone. I'm not happy about it, but I'm glad he was tank raised and not wild caught. That would have been bad.
I am going to give kalk a try in the 55 before I put anything else in there. What size is your tank and how are you planning on doing it?
Thanks,
tiff
