We recommending using the bath treatment method for p metronidazole-susceptible, microbial diseases of marine and freshwater aquarium and pond fishes. Treatment is recommended for syptoms of hole-in-the-head and lateral line erosion Treatments should be consecutive and uninterrupted and could require up to 10 days. For bath treatments, follow these instructions:
- For optimum results, a minimum 30% water change (using Ultimate® or a combination of Liquid Buffered ClorAm-X® and Stress-X™) must be made prior to the first and each daily retreatment
- use 1 capful (~10g) of Metro+™ for every 20 gallons (76L) of water daily to produce a concentration of 5mg/L of Metronidazole.
- After 24 hours have passed, complete at least a 30% water change before each dosage.
- Continue treatment for 5 to 7 days or until mortalities cease. If no improvement is noted within six (6) days, discontinue treatment and consider other options.
We recommending using the oral treatment method for systemic (internal) infections. Metro+™ can be fed mixed with fish food or used as part of a prepared food. Adding Metro+™ directly to food provides a potentially bitter coating that could keep your fish from partaking readily. For oral treatments, follow these instructions:
- Follow our article on how to make medicated feed using a gelatin based or dry food based mix. The gelatin based method can be used to make a food that sinks rapidly. The dry food based method usually results in a food that will sink depending on the feed ingredients you choose.
- Use the medicated feed you have just prepared in place of your usual diet. Feed at least twice daily the amount your fish will completely consume within a few minutes (no more than 5 minutes). Always remove any uneaten food after the feeding period to eliminate the chances of it negatively impacting your fish's environment.
- Continue feeding for at least three days beyond the disappearance of all signs of the disease you initiated the treatment for. Stop feeding this food once a cure is affected, and NEVER use the medicated feed as a general food when disease treatment is not being attempted. Never use prepared medicated food that is more than 10 days old.
DO NOT OVERDOSE - 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.
