Bath: As a bath treatment use Metro+™ for metronidazole-susceptible, microbial diseases of marine and freshwater aquarium and pond fishes (e.g. hole-in-the-head and lateral line erosion), use 1 capful (~9.7g) per 10 gallons (38L) of water. For optimum results, partial or complete water change (using Ultimate® or a combination of Liquid Buffered ClorAm-X® and Stress-X™) must be made prior to the beginning of treatment and every 24 hours for five (5) to seven (7) days consecutively or until mortalities cease or healing of lesions occurs. If improvement is not noted within three (3) days, discontinue treatment and consider other therapy.
Oral: For systemic (internal) infections, Metro+ can be fed mixed with fish food or preferably used as part of a prepared food. Check out our article on how to make medicated feed. Please Note: Adding Metro+™ directly to food provides a potentially bitter coating that could keep your fish from partaking readily.
DO NOT OVERDOSE - this means you should calculate the actual amount of water in your tank by multiplying the length x width x height and dividing by 238 to get the true gallons. Please also deduct the amount of space consumed by substrate (gravel, sand, etc.) rock, decorations or other things which are displacing water.
NOTE: We do not recommend using any sulfur or sulfinite-based water conditioners with this product. If your normal water conditioner does not list the ingredients please verify with the maker that it does not contain these ingredients. If you notice any rotten egg smell to the product, it likely does have these ingredients and should be avoided as it could cause the product to be less effective and the dissolved oxygen levels to be negatively impacted.
Use Metro+™ for treatment of hole-in-the-head or lateral line disease for freshwater, marine or pond fishes.
