Algae in Koi Ponds, Learn this lesson & have a clear water garden for life! Get Rid of Pond Algae!

How do I stop Algae in my Koi Pond? The Algae problem in Koi Ponds and Water Gardens has been a problem for every pond owner.

Jennings explains how to keep a pond clear. Hair algae or string algae and pea soup green water are issues for some pond owners. Take a few minutes and learn the main causes of algae in a pond. What can you do to prevent algae in a pond. What methods are there for a balanced ecosystem in my pond.

For additional information please write us in the comments below!

What time of year do you get algae?

What type of algae do you have problems with?

Do you have koi and feed them often?

Do you use beneficial bacteria, diatoms, or barley extract in your pond?

Do you have a UV sterilizer and is it helping you with the type of algae present?

Treating Algae or Killing Algae with Chemicals never treats the issue or imbalance in the pond and the algae issue will return. Treat the cause and you will have an easy and inexpensive solution. Jennings dives deep to explain the algae causes and solutions here.

Really impressed that you didn't try to sell algicides or UV sterilizers. Quality and comprehensive guide to a clean and balanced pond ecosystem. great video, and thanks for sharing.

You saved my pocket! We just fired our pond guy that was charging us every 6 month 2000 bucks to remove our film algae. Thank you so much

Gotta love that people in really good shape always find a way to take their shirts off.

To my surprise this is not just another how-to-fix-my-algae-problem video but rather one of the best and most comprehensive video on the topic I’ve seen yet. Great job young man.

[TerryJohnson]

This is the best anti Algae video I’ve seen. Thank you for your help. I’ve learned so much.

I mean it seriously - our small pond has issues and we have done so much... huge help!

I am a new pond owner with plants and goldfish. I have a 125 gallon backyard pond and you really explained everything so well. Thank you!

Saw this dude trying to be "showy" for the lady gardeners...
But quickly realised he still has excellent points and covers everything well.
Great job.
I have the film type and realised it was just me not liking the look more than any actual issue.

Thanks for good and clear information.

We have a 104 gallon pond. A filtration system with UV light (likely a failed lamp) and a waterfall for aeration. The past few weeks we noticed the fish were all congregating directly under the fall. When we looked up that behavior we learned that our pond was in distress. I changed about 1/3 of the water and the fish appeared to do a little better for a day or so, but continued to hang out under the fall. I planned on doing a deep cleaning of the pond. We have been having blooms of hair algae. Upon the start of doing so I discovered two dead fish that were just the previous day seen under the fall. This precipitated a drastic cleaning of the pond - to remove the fish to a holding tank while I drained and cleaned the entire pond. The ENTIRE pond. Took the liner out and pressure washed it to remove the algae and bought a new pump/filtration system with UV. Filled the pond and returned the fish.

We added an air bubbler and air pump to put more oxygen into the water. Also, the potted plants - we took them out of their soil, believing the soil was full of fertilizers. The plants are doing OK with the new water and the fish are now seemingly more at ease in the environment. But now I'm concerned because of your comments about changing the water because I changed 100% of the water from city water. Again, the fish are doing better than before - something I believe was needed to save their lives. We've removed the soil from the potted plants, and plan on a few more plants as well. This, we believe, will give greater chances for fry to survive birth. Formerly there was nowhere for them to hide and the other fish were eating them as soon as they were laid.

We've purchased "Beneficial Bacteria" in the hopes to bring our pond into a better balance. Aside from having subjected the fish to 100% water with no nutrients in it, other than the hard water we have here, we're not sure what to expect. We've been adding rocks (P-gravel) as a bed along with flat stones to provide overhangs for them to shelter under. We plan on getting at least one more plant, something with red leaves, as this is what we've heard from others on YouTube.

Do you have any other advice?

Thanks. Pete C.

[edit] I have a sun shade over the pond. It gets direct sunlight in the morning then all day it gets about 90% sunlight. This was also purchased in an effort to cut down on hair algae. I've never had Pea Soup algae, nor have I ever noticed the short algae you spoke about as the third sort. But upon retrospect my UV lamp must have failed. From now on I will start with new lamps. I may have to find a good source of replacement lamps because the filtration system I am currently using (from the big box store) does not sell replacement lamps. "(

Thank you, thank you! You covered every single algae issue we have encountered over the 20 years of pond fishies. Good info about the filter too.

[anirbansinha]

Algae is not bad. It's one of nature's quick fixes to another problem. Well said.

[anthonyweibel]

Wow, I have been installing ponds for years and this is the first time I have had a straight answer on so many issues I have come across. Thanks!

[cathymaynen]

Someone who really knows the science of ponds.. I have had ponds for decades and he KNOWS what hes talking about.

[johnmichaelireland]

i had to watch it twice. ..
I put on the video, , , , and It was over, , and i realised i had not listened to one word. WoW. Jennings, Beautiful..I got the info second time, thanks for the tips

[sheridandurant]

My pond has a bunch of “pea soup algae” I searched up this video because I want to be able to see my goldfish i’m going to try out some of these techniques. Thanks!

[diy_bulshit]

I bought a lotus plant from your store. Just in 3-4 days it started the coin leaves. I'm building a small still water pond for it. Your video is really helpful.

The best solution (and ecological) is to add plants, submerged or rooted in the water. They absorb nutrients and reduce drastically the algae, and they are very beautiful!!

[nathanielinstasi-cowh]

I stop using chems as of this video thank you
Up until this year never had problems with algae hanging around, but for some reason chems haven’t worked and lost some fish. We have bubblers and water fall aerating but must have taking oxygen out koi fish are most affected. Little fish and comets survived the hits. We are using now the bails and barley extract we recleaned our plants and remove old over grown plants. So far it helped out. This was the fourth time clean bottom of pond.
Thanks Nate

[Moamanly]

I came on here fully prepared to argue in algae's defence!
Happily, that is not necessary.Great video.
