Dear Ms Shangxia Song,
I have been plagued with blanket weed in my fish pond for the past 2 years. I have endeavoured to clear using a variety of chemicals and crystals all to no avail. The only thing that disappeared was a great deal of my money, thus in need of seeking a permanent resolution to clearing blanket weed. This blanket weed also continues to adhere to the waterfall surfaces. I visted Maidenhead Aquatics here in UK to discuss my problem. They advised that my problem would be solved totally if I used your Itronic IT-05 in-line system.
Before I procedd to purchase I would like to be reassured by Velda that your product is guaranteed to permanently clear blanket weed.
I await your reply with hope.
Thanks and regards
Mr Gordon Bridger
