As some of you already know, I have added Mandarin Dragonets to my main tank. I waited 3 years, did all the research, introduced a large supply of Pods and Rotifers, started raising baby brine shrimp, and baby proofed everything for my new little ones. So how did I over look this one very important feature....who knows? I changed the water on the main tank this weekend and was going to add my A, B, and Buffer. Then it occured to me, I'm not sure if the Mandarins can deal with the stress after I add these chemicals. I believe A, B, and the Buffer are just a combination of Iodine, Calcium, and Magnesium. Not sure but that's the idea I have and has been in my head for years. Will the Mandarins be OK if I add these to my tank. I'm planning on adding them after work so any thoughts would be appriciated.
