Get rid of algae in your pond Naturally!

Algae in a pond can be a real pain! Especially in new ponds as you wait for the ecosystem to find its balance.Sometimes the water turns green due to single celled algae. While other times its the string or hair algae that is a problem.
If green water is your problem the solution is more nitrogen processing bacteria. The best and most natural way I find to achieve this is adding in a bog filter. Bog filters are cheap and easy to make yourself. Ive made quite a few and this playlist will help you build one yourself- • OZPOND DIY POND FILTER...
If string algae is giving you grief and you live in Australia, I've found diatomix from algaenviro to be quite effective. If you want to give it a try you can visit their website- algaenviro.com.au/garden-ponds/ and if you use the code ozponds you will get free shipping.
If you don't live in Australia you could try nualgai- amzn.to/3gTrt4f (amazon affiliate link). It also promotes the growth of diatoms to outcompete problem algae.

You really inspired my bog filter i made for my turtle and fish tub. The water has never been so crystal clear. I probably watched every video you've made 4 times haha. Thank you sir.

[@Ozponds]

That’s great to hear Chad 👍

[@xxbladexx4471]

I started to have this problem again. I had it when I made my pond but it went away and snow is back and worse then ever 😭. But I will buy that thing you used and hopefully it goes away. I hope I get this fixed soon because it makes my pond look so ugly. I love your videos they help a lot

[@daniellurkin]

Hey I bought that diatomix for my pea soup 5000l pond.....it bloody worked ,I can't believe it,thanks so much...it was getting me down for so long.

[@Ozponds]

Great to hear 👍

[@dannymaroudas313]

Thanks for all the great ideas! After fallowing your plan for bog filter, my pond is now gin clear. Patience is key, as you mentioned it takes time, but well worth it.

[@Ozponds]

Works every time 👍

[@rachelrose8571]

I have a new pond that recently had a string algae outbreak that was cleared up thanks to nualgi. Thank you for the recommendation

[@Ozponds]

That’s great to hear. Thanks for letting us know it worked 👍

[@xxbladexx4471]

This is the video that I needed

[@DaveJonesAustralia]

Thanks Kev, just bought the 1 litre bottle to try - the special offer made the difference. My water is ok but every fortnight I still have to remove a little algae and some floating plants; this may help reduce that growth a little more.

[@Ozponds]

🤞Dave. 👍

[@QuadView]

I can greatly agree with your comment about goldfish and string algae and even other algae. My goldfish can't swim or get to my bog filter area. That area has about 1"-3" of water, perfect for birds to clean themselves. The algae grows in the bog. But no were else because the fish eat it. In fact I break off the string algae from the bog and let it float into the area the goldfish live, they eat it up. Though I noticed now, after about 6 months, that the string algae is mostly all gone. I guess my ecosystem is working better now. I think I cycled through the "new pond" syndrome. I am using a weekly bacteria powder. Thanks again for your great videos.

[@Ozponds]

That’s great to hear mate👍

[@kerrykorberg9537]

Thank you for all the information. I'm a new subscriber. Our pond is new about 450 square feet and 30 inches deep with some large goldfish and a small bog garden. Green peasoup algae is a problem. We have a shallow well with good clear water to fill the pond. I am adding clean water continually and am thinking of pumping water back out into a gravel filter and back into the pond in a waterfall for aeration and circulation? I would be very grateful for your suggestions and opinion. Thank you Kerry .

[@Ozponds]

Sounds like the bog isn’t big enough and obviously I also don’t know how it was designed. I openly share what I do in the hope it helps others with their ponds.

[@suegoetz1221]

I just bought Nualgi. I'll let you know how it goes.

[@eloisecamire3741]

Hey Kev, just hoping you are not affected by the terrible flooding. just saw this on the news. Take care.

[@Ozponds]

Thanks Eloise. We are safe and sound. The floods are much further north.

[@tjharlow5498]

THANK YOU SR.☺❤❤❤!!!!!!!!

[@Ozponds]

You’re welcome 👍

[@davehall611]

Algae can also be your friend by consuming excess nutrients produced by overfeeding, too many fish, or biofilter interference, ie cleaning, treating problems, etc. To speed up the process of algae elimination, just get some regular food supplements of folic acid. I used 800 mcg and added a dozen for so daily until the algae clears. The folic acid feeds the bacteria so that they grow faster, stronger. The bacteria will also mature faster coming out of winter, and last longer going into winter. Folic acid is very cheap!

[@Ozponds]

Yeap I like a little algae. Great tip on the folic acid 👍

[@cynthiamolenaar770]

Oh wow thanks for the folic acid tip! I’ll try that for sure!

[@user-ef6jh5fj3y]

I study diatoms and as I was watching your video I was thinking "he needs to add silica'" lol! Light, phosphorus, silica and nitrogen are the most important factors to regulating diatom growth.

[@Ozponds]

Can you tell me more about diatoms and their benefits or even any downsides (if there are any)? In regard to a backyard pond.

[@user-ef6jh5fj3y]

@@Ozponds Nice to hear from you - your videos are really good. I'm going to try another water garden pot after seeing your suggestions about filamentous algae. I study algae and unlike most scientists, I study how to make MORE algae not less. So it's like the flipside of what you're doing but there's lots of commonalities. One important thing to note is that "algae" is actually a *bunch* of things - there's microalgae vs macroalgae (think green water vs kelp). And then just among microalgae there's three very different types of organisms called "algae": 1) there's actual green algae (little green balls generally); 2) there's diatoms (silica shell and called "brown algae"); and 3) there's blue green algae which is really cyanobacteria - so it's a bacteria, aka prokaryote vs the other 2 which are eukaryotes. All the beneficial bacteria are prokaryotes too. And what you say is exactly right: it's the invisible nutrients that are determining what happens in the pond. If you add silica and maybe scrape off some brown scum off a rock in a river or lake into your pond you'll get a nice culture of diatoms going.

[@Ozponds]

It’s a fascinating subject. What a wonderful job you have!

[@nazeemsultan123]

Hey Mr Ozpond.. i just finished building my outdoor pond. 80% of the build was copied from you. Thanks man

[@Ozponds]

I’m happy you’ve found my videos helpful 👍

[@brianward-lx4up]

G’day Kev, first allow me to congratulate you on the quality and quantity of your videos, impressive! Secondly I am somewhat confused as to how you are contactable, your whereabouts as to where you do your business.😊

[@Ozponds]

I’m just DIY. I share everything I’ve learnt openly on my website and here on KZbin.

[@brianward-lx4up]

@@Ozponds thanks for your reply,Kev, I thought with all your expertise you must have a business. I’m eight five this year an starting digging my pond, hope I’m doing it right and grateful for your help , Brian

[@Ozponds]

@@brianward-lx4up good luck Brian. I hope you create something you’re proud of. 👍

[@phillynch9514]

What about larger ponds about 50 yards by over 100 yards? In the hot weather ponds in my area, north east, the algae goes crazy during the summer. It looks awful and ruins recreation fishing. Catch and release.

[@Ozponds]

The guys at algaenviro specialise in big ponds. Would be worth sending them an email 👍

[@FredaFlynn2008]

I’m in the UK and can’t get Diatomix so is it basically diatomaceous earth?

[@Ozponds]

Kinda. I’m not the manufacturer, so I don’t know the exact formula. It’s predominately silica as that’s what the diatoms need for their bodies.

[@xxbladexx4471]

I am on the US. do they ship to us also or not ?

[@Ozponds]

Nualgi does but not diatomix. Still manually remove as much as you can while you are using the product. Also you won’t need to feed the fish much or at all as the diatoms will feed zooplankton that the fish will eat.

[@JuanMiro507]

I want to build a somewhat small pond. I dont have access to electricity... so how can i use a biofilter if there is no water movement? I don't want mosquitos nor algae...

[@Ozponds]

Check out my videos on ponds with no pumps, especially the wine barrel one. This has a false bottom and the results I’m getting are amazing! Im going to make more ponds like this cause they cost nothing to run and look awesome! Still clean, clear water.

[@JuanMiro507]

@@Ozponds Thanks, i'll watch those videos... I want make a pond 6-8mts2 in size. (it's not that small hehe) and is gonna be mainly for birds as where i live here in Panama (Tropics of Central America) i get lots of birds. i do want to use some water plants and well i'm gonna try to see if i do a biofilter and have some solar pump or something to have the water going to the filter... but definetely there is no electricity on my plan..

[@Ozponds]

Yeap I would definitely do the false bottom. Even though there is no direct circulation the water still moves through the substrate and that is going to provide you some kind of biological filtration. Wether it’s enough to deal with bird poo, I’m not sure. I would love it if you let me and everyone else here know how it all turns out 👍

[@trixie1636]

I have green algae AND string algae but clear water ¯\_(ツ)_/¯ I’ve dosed both my little ponds with algae fix and it hasn’t helped much. My hornwort and water lettuce all have algae on them.. even though I’ve read both help with algae 😑 I’m in Miami, Florida so it gets hot and sunny most days here, I recently got a shade for the ponds since summer will be crazy hot, hoping this will help.

[@Ozponds]

I still think good filtration is the most important element. A properly sized bog filter is my preference, but lots of other options.

[@trixie1636]

@@Ozponds thanks for responding 😊 I haven’t crossed that bridge to bog ponds yet. One is a little half whiskey barrel (15 gal) and the new one is a 40 gal, I could add one to somehow, but that seems so advanced for me 😰

[@ChristianJamesPhoto]

have you tried the Diatomix in your smaller tubs?

[@Ozponds]

I’ve just started. In the baby fish tubs I’m curious to see if it helps them grow. I’ve also just started dosing the anoxic filter pond. I’m having all kinds of problems with algae in that thing.

[@DEXTER-TV-series]

You get rid of algae by... another algae! 😆😃😄

[@Ozponds]

😂 this is very true. Diatoms are a type of algae 👍

[@frasermay7825]

too bad Diatomix isn't available in the UK, unless someone knows different...

[@Ozponds]

They’ve started shipping to the US. So might just be a matter of time. Could be worth sending an email.

[@DEXTER-TV-series]

Why do you call algae "problem" ?

[@Ozponds]

It doesn’t bother me, but it annoys lots of people. That the nature of KZbin people look for answers to their problems. People search how do I get rid of algae, so I made the video 👍

[@barritoes]

Hydrogen peroxide works well.

[@Ozponds]

I tried it and made a vid 👍

[@CardBoardBoxPro]

phew that's pretty cost prohibitive.

[@Ozponds]

It’s not really. A bottle will last me a year. And I’ve got lots of ponds.

[@CardBoardBoxPro]

@@Ozponds $300+ USD? Eh

[@Ozponds]

What product are you referring to? Im using diatomix at $99 Aussie dollars a bottle. That’s about $66 USD.

[@CardBoardBoxPro]

@@Ozponds the IV which is the only one available to USA. It's much more expensive. In was attempting to buy it but PayPal wanted $299 usd

[@Ozponds]

I see. That one is a stronger concentrate. What about nualgi? That should be available in the US. I’m also about to do a trial on hydrogen peroxide, that should be even more cost effective. Just don’t overdose!
