Well did my bi-weekly tests and noticed my ammonia is .25 nitrites are 0.1 and nitrates are 10 ppm. I add phytoplankton, calcium, strontium, and iodine. My other parameters are good. I haven't added any livestock and up to this point everything was good. To be sure I did a small water change (4 gallons) and used distilled water. What may be causing this? <img src="graemlins//confused.gif" border="0" alt="[confused]" />
