If your going to pick up your test kit tomorrow i would leave your dosing until you have tested your waters chemistry. Not knowing your current ammonia level(ppm) could end up you overdosing.ok so the royal mail tried to deliver my api kit today but as i wasnt in they just took it to my local post office (not sure why they couldnt leave it round the back like they did with my £700 laptop!)
So anyway in the interests in keeping the batcteria in my mature filter medi should i add any more ammonia? say a few ml just to keep them happy?
