Setting up my first tropical tank, Juwel Rio 125. I dechlorinanated the water and latter added Safe Water and plant food for three planted plants. I soaked a medium piece of bogwood for four days in a bucket before introducing. After about five days a white stringy fur mould like growth has appeared, is this normal and will it disappear? I thought about getting a few Zebra Danios this weekend to get the tank cycling now i`m not sure
