Need to get some answers/opinions for CA test kits. I tried using the Aquarium Systems test kit (box with pink little polyps all over) and the Hagen test kits and got some crazy results. THe Aquarium Systems gave me a reading of 525 mg/L and the Hagen wouldnt even give me a reading. No matter how much of the 3rd liquid I would drop in the color would not change from pink to blue so im assuming that my calcium is over 1000 or something. Anyone have any suggestions or experience with these test kits. Im just dosing kalk or kents liquid calcium. :withstupid2:
