Ok guys so my tank is up and running. I have included photos of my tests below. The tests have been completed after adding dechlorinator and biological starter. I am also using a filter that has been used previously by the person I purchased the tank from I just rinsed these under tap water. I’m still rather confused by how much ammonia I need to add to the water. I have the Juwel Vison 180 led. I worked out that I have added around 128litres water to fill the tank.. can anyone help... pretty please ?
