Hey, everyone welcome back to the channel adam here with indie, farmlife standing out on the dock and I'm going to do some long overdue maintenance on the pond.

Most of my time, this spring's been dedicated to the house.

So I really haven't done what I needed to do to keep this pond, looking nice.

So today, we're going to talk about algae, blooms how to prevent them and how to combat them if you have them.

So as we pan around the edge of the pond, you're gonna see that we have some filamentous algae that started to pop up on us.

Now, what this stuff does is it grows from the bottom up breaks apart and floats, and then will settle and reattach at the shoreline in other locations out there in the middle, you can see some floating, but the higher concentrations of it are definitely on the shoreline.

The silver lining to this kind of algae is that it's, not blue green algae, and that it's, not technically harmful, but still a nuisance.

So what gives rise to these algae blooms? Well, there are really three factors, one it's having low dissolved oxygen levels in your pond, which we currently do, because we have nothing turning the water yet aeration is something I'm going to be working on here shortly and I'll make some detailed videos about that decision in process.

The second factor is high nutrient levels in the water again.

We don't have anything turning the water, which means we don't have a lot of good bacteria in the water, which would consume these nutrients.

We don't have fish yet helping out either.

And the third is sunlight penetration into the shallows pond is a great way to prevent sunlight from reaching the bottom.

But as you can see behind me, the pond's kind of greened up right now and it's, not as blue as it once was so sunlight is able to penetrate into the shallows.

And like most things in life prevention is much easier with algae than controlling it.

Once you already have it and the best prevention methods are aeration and pondi.

I do have the latter, but the former I don't currently have.

And so we are where we are let's, talk about what we're gonna do to clean this pond up also while on the subject, I should mention that we don't have suspended algae in this pond.

This pond is green because of the dye or the remaining dye that's in there, I'll grab a water bottle, real quick and just show you how clean the water is in this pond.

First show, you guys some of this water there you go fairly clear stuff actually looks pretty darn good.

No suspended algae.

Just the floaters so what's, the answer, at least, I hope copper sulfate, never used it before, but like most things I do.

I did a lot of reading ahead of time.

And I've read lots of good things.

So you can buy this stuff in a lot of different places.

I know, tractor supply does carry it.

I got this from amazon shock.

These are little dried pellets and so just dissolve it in water and spray it on top of the algae.

I think from what I read roughly five pounds of this, which is what this one here is for a one acre pond, which is what we have, even though it's not completely full and dissolve it in about three to four gallons of water I'm, just gonna put it in a four gallon backpack sprayer and spray it on all of this a couple items to be aware of if you do go, this solution, you're only supposed to spray about half or a third of the pond in one round, because this will kill all the algae on contact and then deplete your oxygen levels.

This is mostly, if you have a lot of aquatic life, fish, etc, we don't so I'm, not really too concerned about depleting, the oxygen levels, they're already really low.

So I may go ape as I typically like to do for that very reason I just mentioned you're also supposed to wait about 14 days between applications again, not a factor in what I'm doing here.

So I'm, just gonna spray and pray baby and see what happens.

So I'll, uh, mix some of this up in a backpack sprayer, put that on.

It will turn the pond a little bit blue because of the color itself, but then I'm going to throw a lot of pawn dye in as well.

So I'll, first mix up that copper, sulfate and get that sprayed show you guys that process real quick and then we'll toss some dye in and I'll probably circle back in about 36 to 72 hours and give you guys a look at the pond.

Okay, so I got batch mixed up.

I ended up only going with half of the five pounds.

So two and a half pounds of copper sulfate into the four gallon tank.

There.

I probably end up spraying all of it anyway.

But I want to make sure I have enough coverage.

I don't spray through the four gallons too quickly.

So it may take me a little bit longer to spray it since I'm gonna maybe go through it twice.

But I wanted to make sure at least got coverage on everything.

Once plus, I thought I'd dissolve a little easier.

I did like a gallon a half of water, hot water, and then poured that in and then topped it off.

I am putting on some latex gloves, some black ones to help pull the sun in a little bit more since it's, you know, 80 degrees, and I've got a four gallons of hot water in my back.

Now, this stuff can be absorbed through the skin though so the device will stay out of the water for about 24 hours after you spray by then most the copper sulfate will have dropped to the bottom of the pond.

No longer be suspended.

It's gonna take a while.

So I was able to make almost a full lap around the pond with that first batch now I'm gonna mix up the second batch and hit it again.

I won't video that part.

But you guys got the idea actually, even right here in front of me, looks like it's already kind of making some of the stuff sink to the bottom.

It could have been just a spray, though knocking it down also when I do go to put the dye in well, two things one, I think I might put it in an old sprayer.

I have because I think it'd be really cool to see dye sprayed into a pond.

As opposed to tossing.

It I'll show you the far side of the pond, where the edges are a lot steeper, much less algae growth over there than in the shallows, where sunlight can penetrate I'm, not sure if I mentioned that or not but that's, something you could always do whenever you build a pond is cut your edges, even steeper like that far side.

So you don't have to fight this stuff.

Okay, I got all that sprayed in.

You can see some of the blue floating there.

But now it's time for the real blue.

And the stuff that's more fun.

I'm gonna put a gallon of pond dye in that sprayer probably against my better judgment, but sounds like fun could be an absolute mess, but I'm gonna go to the far east side of the pond, where the wind always comes in this way off that field.

So won't be spraying against the wind, hopefully, and it could be fun also if you've never used pondai before or ever seen in action.

I encourage you to flip back to the video I posted last year and I'll link it above.

Uh.

When I first put this dye in the pond was completely fresh and had no dye in it.

It was pretty incredible to see it work its way through the pond and to go from nothing to a tropical oasis, get a nice green color.

Now, this baby's going to be as blue as that raft over there by the end of the day all right, wind, don't fail me.

Now this could be a disaster, nope, it's, awesome.

That might be the coolest thing I've ever done out here.

I like the shelf that makes as it makes its way across the pond.

I spray a little bit over on that far side where all the algae was just.

So I know that we got it covered.

Well, I got probably about a quarter gallon left.

I think that's all I'm going to put in I'm not going to probably do any more than that given that it already had some color.

I think it didn't take as much as it did last summer.

Can't, take it out once you put it in okay.

So I got a gallon or just over sprayed into the pond.

I don't know if the camera will pick up the shelf cloud that's kind of moving toward us in the water or not, but it's making its way over see how my algae's blue over there.

Now.

And here I'll give you up close of it.

And a high concentration very very potent stuff.

A lot of times in the comments, my other video, people will ask how do you swim in that surely it stains your clothes and skin right? Well in the undiluted form, yeah, absolutely but 24.

48 hours.

It'll.

Be fully dissolved in the water and it.

Doesn't stain your swimsuit.

Your skin won't hurt any fish, it's, great stuff, and it looks really pretty okay.

So the copper sulfate is in hopefully it does its job.

Uh, that's kind of a band-aid it's, not really the fix that we're after, but should at least clean things up for a while until I get some air out here to start turning things.

The dye is a preventative measure it along with air go a long way, but I'll circle back in probably 48 hours 36 hours something like that and give you guys a shot of the pond, hopefully I have good news all right.

So here we are about 72 hours later, obviously, the dye did a wonderful job.

And the algae's starting to die off.

You can still see quite a bit floating out in the pond, but that's, actually a good thing.

As you look at the shoreline, you can see that it's dying from where it was actually attached, and then just kind of floating.

So that stuff should sink to the bottom and be clear before too awful long, maybe 24 hours or so.

But you can see the shoreline here, how thinned out it is now.

So the copper sulfate seems to be doing its job thus far, again, more of a band-aid than a permanent fix, but I'm pleased with the results so far.

So if I have to use this on occasion, I definitely will in the future, but getting some aeration out here to turn this water is the in-game goal, hopefully that was helpful and informative for some of you out there who might be in a similar situation.

And if I did anything wrong or way off base, please comment below I love hearing from you guys and learning from the experience of others.

So if you would hit that subscribe button, come back and see us we'll, see you guys next time and for further documentation purposes, this is after five days, looks a whole lot better and look for a video regarding our new canopy for the dock here in the next couple weeks, big improvement.

Pond Algae Prevention & Control - Our Pond Looks BEAUTIFUL! - Copper Sulfate, Pond Dye and Aeration? ›

Copper sulfate can be toxic to fish and other organisms. Copper sulfate results in copper build up in pond sediments and creates a sterile bottom in the pond. Besides many important organisms, it kills beneficial bacteria.

Can you put too much copper sulfate in a pond? ›

Copper sulfate can be toxic to fish and other organisms. Copper sulfate results in copper build up in pond sediments and creates a sterile bottom in the pond. Besides many important organisms, it kills beneficial bacteria.

How long does it take for copper sulfate to work in a pond? ›

Liquid copper sulfate is best applied by using a broadcast sprayer. Within about 48 hours after application, the algae should be brown and dead or dying.

How much copper sulfate should I put in my pond? ›

Generally, copper sulfate crystals should be used at 5 pounds per acre of pond. So, for instance, if you have a 1-acre pond, you should dissolve 5 pounds of crystals in three gallons of hot water first. For best results, treat your pond using the spraying method to kill the actively growing algae at the top and bottom.

What is the best pond dye for algae control? ›

Blue dye is also a good choice for algae control, being able to block a large chunk of UV light from entering the water. It's less effective compared to black dyes, but should be more than sufficient for algae control in most ponds. It will also help deter predators and make fish harder to see deep in the pond water.

How much aluminum sulfate does it take to clear a pond? ›

Per Acre Foot Aluminum Sulfate (Alum). Alum is the most effective treatment for clearing muddy water caused by colloidal clay. Application rates for alum are recommended at 25 to 50 pounds per acre-foot of water depending upon the concentration of suspended clay particles.

Does copper sulfate get rid of algae? ›

Copper sulfate will eliminate filamentous algae and planktonic algae. We recommend using one pound of copper sulfate for each 5,000 sq. ft. of algae growth.

How much copper sulfate per gallon of water for algae? ›

In a plastic container dissolve one teaspoon of copper sulfate dissolved in a gallon or so of water. This will treat a 300 square foot area with an average depth of 1 foot. For example, a 600 square foot area that is 2 feet deep on average will require 4 teaspoon of copper sulfate.

Can animals drink from a pond treated with copper sulfate? ›

Copper sulfate is a way to treat the water and kill the algae but can lead to high copper levels in the water, which can be harmful to cattle. Sheep are particularly susceptible to copper toxicity.

Can you use too much copper sulfate? ›

Tissue corrosion, shock and death may occur after exposure to large doses of copper sulfate. Damage to blood cells, liver and kidney has also been reported.

How do I get rid of algae in my pond naturally? ›

Barley: Barley is the perfect solution for maintaining a clean and clear pond naturally and is safe to use in ponds with fish and other wildlife. Barley can be used during the winter months when other pond treatments are ineffective. Barley products are available in a variety of different forms: Barley straw for ponds.

What is an alternative to copper sulfate for ponds? ›

What are the safe (and long-lasting) alternatives to copper sulfate? A much safer alternative is a copper complex or chelated copper. Treatments like Cutrine Plus and Cutrine Plus Granular are examples of these. These treatments contain only 7-9% of elemental copper, versus 25% in copper sulfate.

How long does copper sulfate stay in the water? ›

In hard or alkaline waters, copper sulfate tends to settle to the bottom within 24 hours after application. Chelated copper remains in solution longer, allowing for a longer contact time with the algae.

What happens if there is too much copper in water? ›

However, it is possible that eating or drinking too much copper can cause headaches, vomiting, diarrhea, stomach cramps, nausea, liver damage, and kidney disease. High levels of copper may damage red blood cells and may also reduce the ability of red blood cells to carry oxygen.

How much copper sulfate can be dissolved in water? ›

It has a solubility of 31.6 g/100 mL at 0˚C and 203.3 g/100 mL at 100˚C.

What effects does copper sulfate have on ponds? ›

Copper sulfate can accumulate in pond sediment over time, leading to long-term exposure for aquatic life. This can lead to chronic toxicity, even if the copper sulfate is no longer added to the pond. Copper sulfate can also harm beneficial bacteria for maintaining a healthy pond ecosystem.
