I use the Aquarium Phar. Freshwater Master Testkit, the wet kind. I currently use AmQuel but the bottle is about out so its time for a new dechlornator. I was wondering if the AmQuel gives false positives for ammonia with my test kits? If it does can someone reccomend to me a dechlornator that doesnt effect test results. Hows the Marineland stuff, Bio Safe?
