API General Cure is a quick-dissolve powder formulated for freshwater aquarium use, combining two active ingredients that work together against a broad range of external and internal parasites. The powder is measured directly into aquarium water, where it disperses without discoloring the tank. A full treatment cycle involves an initial dose followed by a second dose 48 hours later, after which a partial water change and fresh activated carbon are recommended to complete the process. The formula is compatible with tanks containing live plants. It is offered as pre-measured powder packets for smaller or single-treatment use, or as a bulk jar with an included measuring scoop for larger systems or repeated treatments. Aeration should continue throughout the treatment period, and carbon or filter media should be removed before dosing for best results.
