Hi, I am new to the forum and new to planted aquariums. I currently have 3 amazon swords in a 56 gallon column tank with 6-24" 6500K T-8 bulbs above it (medium lighting?). My ammonia and nitrite levels are at 0, and nitrate is usualy between 5 to 10 ppm. The tank houses about 10 red fire guppies, and one chinese algae eater. My question; I recently started adding flourish excel and flourish iron. The flourish iron I am most uncertain about. I purchased a hagen iron test kit to test the iron level of the aquarium. After my last PWC I added a whole capful of iron supplement to the water (instructions on the bottle of iron supplement call for 1 capful for every 100 gallons). When I tested the water 2 days later, the iron test kit indicated that I had no iron in the water. I followed the exact directions that came with the test kit, and have reapeated the test several times, but have never had results any different. I would greatly appreciate any feedback on whether my test kit may not be good or if I have simply missed something.
