I have a 55 gallon tank with rummynose and blue rams. Everyone is healthy and rams show great color and rummys are shiny silver with bright red head. I have an apI master test kit. When I take a nitrate reading in my tap and tank It shows 80ppm if you hold it right against the card, and it shows 40ish if it's held an inch or so away. I tested bottled water it showed 0. I bought some apI test sticks in a panic and they read 20-30 In tap and tank. Chain fish store tested it and they said 0 but I do not trust that it was done properly there soo. Then again all fish are super healthy. My best guess is that it's around 30 and that the the liqued test is either too hard to read or faulty. What do you guys think? Thanks
