Kim W. – “2 weeks ago it was brown water…”

“My fish look happy and healthy.”- Kim W.

Kim lives in Caledon, Ontario Canada. She shared with us on Facebook how algae had been effecting her pond water quality and the mood of her fish. Look at this big piece of algae that she pulled from the skimmer!

Nualgi Ponds often does not work overnight, but in Kim’s case, she is experiencing crystal clear water after only 2 days! It’s exciting to get these types of posts on our Facebook page when Nualgi users are finding they invest significantly less time in pond algae control. Our goal is to have happy and healthy fish that have a well oxygenated ecosystem.


May 21st, 2017 – “Pulled this huge piece of algae out”

“Put some Nualgi in my pond 2 days ago and just pulled this huge piece of algae out of my skimmer – pond is clear. This is the second huge ball of algae I’ve pulled out of my skimmer. Before Nualgi I would struggle just to detach it from the walls.”

Kim asked us a great question:

“I have a furry like algae on my walls it is not stringy and I am not sure if it is good algae or not?”


Our Pond Professor’s answer:

“That is the good carpet algae… part of the ecosystem. Fish nibble on this.”

June 27, 2017 – “It cleared up in literally 2 days!”

“I bought it in the fall used it once then closed my pond for the winter. When I opened my pond 2 weeks ago it was brown water, I put some Nualgi in and it cleared up in literally 2 days! My fish look happy and healthy. I live in Canada and I just ordered another bottle!”

July 20, 2017 – Koi Pond Video Update

WOW – We are impressed by this water quality. Must be because Kim used Nualgi once in the fall before closing her pond, which led to a quicker pond opening this year!
