Izeki Super Clean C helps to break down the organic matter in your pond and lower the levels of ammonia. We find this product very good and when used in conjunction with Magic Powder, reduces blanket weed.
One more thing, this product really does add a sparkle to your water!
Add 10grams per 1000 gallons per week for the first month and then 5 grams per 1000 gallons per week afterwards, if required.
To get the very best results use Magic Powder and Super Clean C together.
