I have an Interpet Fishbox 60 (64 litres) and I set it up and stocked it well with plants 4 days ago. I have added Filter Start and Nutrafin as recommended to me. After taking a water sample my local pets at home today I discovered that ammonia, nitrite and nitrate levels are extremely high, is this correct? I am awaiting delivery of an API Test Kit so that I can monitor things daily. Can anyone offer advice on whether I have done things correctly so far and what I should do next?
