So some how i lost one of my bottles of api nitrate test. My tank (125 gal) has been up for a 1 1/2 years. water changes were very seldom like maybe 4 small changes in that time (i know bad but that is why im changing my ways). i always tested the water and it allways showed 20 ppm. I have now bought a red sea test kit and have been doing water changes again. after a few water changes i tested it and it was 60 ppm :O . i then did a few more water changes and ran the water to the lfs to use her api test kit. it once again tested at 15-20 ppm. is there really that big of a difference in those test kits. and which should i believe, my fish seem fine and my corals are ok even the birdsnests and monti seem fine. Any help will be appreciated. Water changes on a 125 are a pain... cant wait till i have my own place and can design a easy water changer.
