Mr Koizumi Active Lacto-Bac is a probiotic water treatment formulated to enhance the health and vitality of koi and other pond fish. It contains a blend of beneficial components, including enzymes, minerals, probiotics, lactic acids, ferment, trace elements, vitamins, and essential amino acids. These ingredients work synergistically to prevent fungal infections, fin rot, and various bacterial infections. Additionally, the product promotes faster healing of wounds, minimizes scar tissue formation, stabilizes pH levels, binds ammonium and nitrite, supports the biological filter, reduces algae growth by depriving them of nutrients, strengthens the immune system, and improves digestion in koi and other fish.

Dosage and Usage Instructions:

  • Initial Application: Shake well before use. Dilute 500 ml of Mr Koizumi Active Lacto-Bac with lukewarm water (between 24 °C and 28 °C) and let it sit for 5 to 10 minutes. Then, spread this mixture over the pond. This dosage is suitable for 10,000 liters of pond water.

  • Maintenance Dose: Every 14 days after the initial dosing, apply 250 ml per 10,000 liters of pond water.

  • Post-Application: After adding the lactic acid bacteria, temporarily switch off the UV or/and Ozone and any protein skimmer for 24 hours.

  • Feeding: You can also add the lactic acid bacteria to the food, but only prepare enough for one or two days.

When to Use:

  • When new fish are introduced to the pond

  • Immediately after significant water changes

  • Immediately after using medication

  • When ammonia, nitrite, or nitrate levels are high

  • As a booster for a strong immune system before winter or spring

  • To improve the mucous membrane and resistance

  • To support recovery after fin rot, fungal infections, or injuries

  • To speed up recovery and limit scarring from transport-related damage

  • To alleviate stress in fish for any reason

  • To address bacterial problems such as Aeromonas and Pseudomonas

  • To reduce excessive algae growth by removing their nutrients and maintaining a natural balance in the water  

Mr Koizumi Active Lacto-Bac is available in 1-liter and 5-liter bottles, with 1 liter treating up to 20,000 liters of pond water  

Please note that this product is not a medicine but a supplement designed to promote overall fish health and pond water quality.

Waste of Money and Time
It’s useless buying this protection plan. They will not help you with your issue. They will refer you back to the seller. What’s the point of buying a protection plan when they refuse to help? I DO NOT recommend purchasing this plan. Total waste of money and time.

Quick and easy to file a claim & get resolution!
I bought a blender from Amazon about 18 months ago and at the same time, purchased the Asurion policy to cover it. The glass pitcher cracked last week and I filed a claim with Asurion. Having never used Asurion before, I wasn't sure what to expect but I was blown away by the ease and speed with which my claim was resolved. Immediately after submitting the claim, Asurion sent a pre-paid shipping label with clear instructions on what to do next. After packing up the blender, taping the label on the front of the box (I had kept the original box the blender came in), and dropping the box off at the UPS location near me (Asurion's instructions included addresses for 2 drop-off locations in my tiny town), I had a refund in my email within hours. I was able to add the refund to my Amazon account simply by clicking on a button in the email and there it was, a credit in my Amazon account! As I said earlier, I'm blown away by how easy it was to file my claim and get a refund. Asurion made the entire process so effortless! Since the blender I had purchased is no longer available, I ordered a different one from Amazon (it arrives today - yay!) and I can guarantee you that I also purchased the Asurion policy to cover it. Thank you, Asurion, for making the process so easy and the resolution so fast.
