Medications have become so much more effective in the last few years and we, at Aquatic Warehouse, have culled through all the cheap remedies that are not. Be it for freshwater or salt, we have great wide spectrum and pin-point medications and treatments that you are looking for. Be aware that we do not recommend antibiotics in a reef or saltwater fish tank. For these we use a cheap 10 gallon glass tank with daily water changes with aeration and a heater.
