Hi all, new to forum. I recently assumed responsibility for a new 310 litre tank. All was going well but now young Clown Loaches introduced 3 weeks ago have White Spot, and 3yr old Clown Loaches and other fish have caught it. Interpet White Spot Remover advises to remove Carbon and Zeolite Filter Media. I have an Aquamanta 400 External Filter which has "Advanced Ceramic Media" in it. Do I remove this and the carbon
? Urgent help please - thanks in advance!
