“I needed to buy a new UV lamp this Spring. So I thought I would try Nualgi for $35.00 instead. My water is clear and I have no string algae.” – Nancy
Nancy is a koi pond owner and gardener in Winston Salem, NC. With temperatures reaching as high as 100 degrees, it used to be a challenge for Nancy to control her algae outbreaks. Read all forum entries on Koiphen Forum
As an active member of World Wide Koi Club’s (WWKC) Koiphen Forum, Nancy started reporting her observations on her water quality and plant growth as she dosed Nualgi. We are very pleased to receive feedback from an experienced pond owner as we follow Nancy’s journey for a healthier and a more balanced ecosystem.
March 26, 2015 – Bottle of Nualgi Arrives
“I just received my order of Nualgi for ponds and aquariums. On the bottle it says to dose the pond every 7 days. Also to dose first thing in the morning and best not to use my UV. I will uncover my pond this Monday and dose it the same day, after I do an early morning water change and clean my filter out. I will report here the results that I see.”
March 31, 2015 – UV Filter is Removed
“I uncovered my pond today & did a 50% water change. I will want to do another one in a few days, so I am going to wait to add mine until I am doing water changes once a week. It says to dose the pond every seven days.”
April 12, 2015 – Second Dose
“I will be adding my second dose in the morning. So far so good.”
April 20, 2015 – Nualgi is Put to the Test
“I put my third dose in this morning. My pond water has now turned a tannin color from the Oak tree pollen. It does this every year. It was clear a few days ago. I will know if the Nualgi is working once my water clears again.
With my instructions, it said to use it once a week for 4 weeks and if there is no improvement to call.”
April 23, 2015 – Pond During Treatment
“Some pics I took last week. Some Vinca vine growing in the stream. Along with Fiber Optic plants and Liriope. I plant to work on planting Impatiens & Sunpatiens in the stream and pond tomorrow. I also have some Marigolds to try in the pond this year.”
May 4, 2015 – 5th Dose, No Green Water
“I had a tiny bit of string algae form on my waterfall last week , but in the last few days it disappeared.”
“Added my 5th dose this morning. So far no green water. UV hasn’t been turned on. I had a tiny bit of string algae form on my waterfall last week , but in the last few days it disappeared. My pond is clear but I have a very faint tannin color that is will be removed by water changes that I do. So far I am pleased.”

“I am pleased so far that I don’t need to buy a new UV lamp & pay for the electric to run it.”
May 30, 2015 – No More String Algae
“I added my 8th dose after I did about a 20% water change and cleaned the filters. My water is clear.
I don’t have any string algae either. I am pleased so far that I don’t need to buy a new UV lamp & pay for the electric to run it. I will continue on adding Nualgi every Sat. after I do a water change & clean my filters.”
June 3, 2015 – Nualgi Beats Using UV Lamps
“In my case, I needed to buy a new UV lamp this Spring. So I thought I would try Nualgi for $35.00 instead. My water is clear and I have no string algae. So far so good. I have not bought a new lamp and I am not having to pay for electricity to run it. I am very pleased with my results so far. Maybe the real test will come in July & August. I plan to keep using it once a week after a water change and after I clean the filters. I hope I continue to have clear water & no string algae using Nualgi. This sure beats buying UV lamps & paying the power company.”
“My water is clear and I don’t have any string algae.”
June 8, 2015 – 9th Dose, Plant growth
“Added my 9th dose this morning. My water is clear and I don’t have any string algae. So far I am pleased.”
“I took theses pics yesterday. All of my Sunpatiens cuttings are now blooming and getting pretty big. I think my Impatiens doubled in size in a weeks time.”
June 14, 2015 – Clean Waterfall
“Here is a pic of one of my waterfall rocks showing no algae or string algae. No green water.”
“The rest of the week it will be around 97* to 100*. I am interested to see if my pond develops any green water.”
June 19, 2015 – My Lotus Bloomed!
“My lotus bloomed. It has a third bloom that may open in a few days. A few water lilies too.”
June 20, 2015 – Threatening Temperatures Approaching
“Saturday I added my 10th dose. This will be a good test for me this week. Tomorrow the temp is suppose to be 102*. The rest of the week it will be around 97* to 100*. I am interested to see if my pond develops any green water. It is clear with no UV.”
June 30, 2015 – Nualgi in High Temperatures
“Last Saturday I added my 12th dose. It was a good test for me with more days at high 90’s & close to 100* all week. No green water. It is clear with no UV. So far so good.”

July 11, 2015 – Nualgi Passes the 2 month Test
“No green water. It is clear with no UV. I like the idea of saving money on my electric bill too.”
“I added my 13th dose this morning. The last two months have been a good test for me with more days at high 90’s & close to 100*. No green water. It is clear with no UV. I like the idea of saving money on my electric bill too. Plus I haven’t had to buy another uv bulb that would cost more than the Nualgi. So far it is a win win for me.”
July 27, 2015 – 14th and 15th dose
“I have used a 14th and 15th dose Nualgi. My water is very clear and I still don’t have any string algae. Because of this my stream looks great too.
My water lilies have had more blooms this summer than they have had in years.”
July 28, 2015 – Nualgi is safe for plants
Windsong A. asked: “Nancy, did you have troubles with string algae before you used this product? I know my pond has a lot of string algae in it, but it is also quite clear, so the main benefit would be on my pond to keep the string algae in check. I do have other plants (mostly water lilies) that will remain in the pond, and my understanding is that this product is not supposed to harm them…true?”
Nancy responded:
“I have had problems, a few times a year, with string algae since the UV doesn’t help with it. Over the years when the string algae started to grow, I would start adding Koi clay and within 24 hours the string algae would disappear.
Since using Nualgi, I have not had any problems this summer at all with it. No green water at all.
In Nualgi’s info, it reads that it is good for all plants in your pond. I have had more water lily blooms this year than I have had for a long time.
I do not use UV because the info said not too, That is why I gave it a try first. It was cheaper than buying a new UV lamp and also I save on my electric by not using it. “
