"With the full long period of sun this year my pond suffered a huge blanket weed bloom clogging my whole pond and bottom drain. It took 2 applications of your product but that cleared it all and my pond is running perfectly and clear. Really pleased with the results"
"I think I need a stronger product to assist with my algae problem. I have treated the pond three times now and added bails of barley straw but alas to not affect. I remove the surface algae but within 10 days it is back."
"Fantastic product use for 2-3 weeks once a week and string algae eaten, also used with Pond Klear Xtra once a week and green water now crystal clear! Super products use weekly as per dose for size of pond. It works!"
"I add Algae Klear Xtra to my pond weekly during the summer months and although it does not completely eradicate the weed it keeps it under control and the water remains clear. Without it the pond would be a solid mass of weed."
"This worked very well to clear an overgrowth of algae that plagued my pond this spring. I used it carefully according to the instructions, needed two doses over a couple of weeks but it did the job, my three 10 year old koi could see where they were swimming again and I was happy with the result. I did use Sludge Clear as well, it all took a few weeks but it did work. Will buy again if necessary."
"Have been using this weekly for five weeks now and a bit disappointed that the pond is not clear of the green algae yet."
"Used regularly (weekly), this keeps the blanket weed in my pond, which gets a lot of sun, under control. I also used the winter product during the colder months. The pond is full of wildlife so no harmful effects on them. Before discovering this product the blanket weed was really invasive. I have been using it for quite a few years now. Company really helpful if you have a problem or question. I only gave it 4 stars because, in my case it hasn't completely eliminated the problem. Would give 5 stars for customer service."
"Worked really well initially, but pond algae now proliferating again. Working on adding more plant cover. ."
"Certainly seemed to have improved the algae problem"
"Repeat customer. Used for many years as works as described."
