Getting a hippo tang this week and I want to be ready just in case it gets ich. I already have SeaCure Copper Treatment, cannot find the SeaTest kit that is recommended with it. I found Instant Ocean Copper Test though which is also manufactured by Aquarium Systems (same as SeaCure.) The ideal dose for SeaCure is 0.15 ppm so I'd need a test that reads that which Istant Ocean Test does. My Aquarium Pharmaceuticals Test is useless as the next reading after 0 is 0.25. Any recommendations?
