100% Natural Winter Pond Care Bacteria that thrives in cold water temperature!

Protect your fish from poor water quality throughout the winter season. Prevents poor winter water conditions, losses and stresses that can cause spring pathogenic outbreaks. Just one easy treatment every other week and your pond and fish will be in perfect condition come spring!

  • Works in very cold water (as low as 35°F)
  • Removes deadly ionized ammonia and toxic un-ionized ammonia
  • Removes toxic nitrites and nitrates
  • Reduces and digests bottom sludge all winter
  • Helps maintain a healthy immune system
  • Will not deplete the oxygen level in your water
  • Reduces spring clean-up
  • 100% natural, NO CHEMICALS, safe for pets and wildlife
Question 1: How does Arctic Blend’s beneficial bacteria remove ammonia from frigid winter pond water when it’s a known fact that “nitrifying bacteria” which keeps ammonia and nitrites at zero does not perform in cold water?
Answer 1: Arctic Blend is not a “nitrifying bacteria”. Arctic Blend’s beneficial bacteria is formulated with billions of natural unique microbes that absorb the ammonia from your winter fish pond water. Then these microbes process the ammonia through their system, rendering the ammonia harmless to your fish. You never have the common “nitrifying bacteria nitrogen cycle” which is, high ammonia then high nitrites and at last, less toxic nitrates when using Arctic Blend. 

Question 2: Why should I worry about the ammonia in the winter months, my fish are not eating so they do not produce waste. No waste, no ammonia?
Answer 2: Your fish produce more ammonia by breathing than they do from their waste. So they are producing deadly ammonia all winter.
