Using Algaecide In Swimming Pool: Algae is one of the most disgusting organisms that can invade your pool.

After water bugs, of course.

Those things are disgusting.

But when it comes to pool ownership, few things are worse than heading out into the backyard for a nice swim and then
finding a bunch of green stuff.

So, you may be thinking “What’s the big deal?

“I’ll just throw some algaecide in there “and it’ll all be chill, daddy-o.”


Well, before you spend money and pour a bunch of algaecide in, is that really the best method to cure algae?

Is it the best way?

I don’t know.

Alright, I have a better idea and I’m gonna tell you about it right now after this intro.

Alright, quick disclaimer, everyone has their own way to maintain a pool just like we all have our own personal truths, but in the end, our goal is to just help you.

And I’m sorry if I missed anything, but if I did please leave a comment and let me know, and also to help your fellow pool owners out.

Alright, so you can get three types of algae in your pool: green, yellow, which is also called mustard algae, and black, the worst and most difficult to remove.

Now, I know algaecide sounds like something that will kill algae just like pesticide kills bugs.

Using Algaecide In Swimming Pool

I don’t know, so many are quotes.

And it actually does to a degree, but here’s the problem.

The active ingredient in algaecide, the thing that actually kills algae is usually copper.

And what eventually happens to copper?

Well, it oxidizes.

It basically rusts, or in copper’s case, it turns green like the Statue of Liberty.

Yes, the Statue of Liberty used to be a shiny copper color since she’s made of about 30 tons of it.

So, what happens if you put copper in the water and it oxidizes?

Well, it could actually stain your pool.

And what if your pool water already

has a high metal content?

Maybe you fill your pool from some sort of high-metal water source.

You will get even more oxidation, which means even more staining.

And you could just fix that, right?

Well, normally to treat high metal content pool water, and to keep it from staining your pool, you need to use a metal sequestrant.

It doesn’t remove the metal.

It actually binds metal molecules together so that they won’t stain your pool and so they can be removed by your filter.

And there’s a problem if algaecide stains your pool and then you use a sequestrant to prevent staining, you’re removing the
algaecide from the pool so you need to add more algaecide, and then that means you have to add more sequestrant.

Then that means you have to add more algaecide, and then you have to add more sequestrant, and then you have to add more algaecide.

So, while you’re sounding like a broken record, that algae is just watching and laughing at you while it continues to make
itself comfortable in your pool.

Not to mention, you’re also wasting a lot of money and time.

So, there is a better way, and the answer will shock you because the answer is shocking.

No, I mean it’s literally shocking your pool with a high amount of chlorine that will actually kill algae dead.

So, here’s what happens, chlorine attacks algae at the cellular level by oxidizing it, which means removing some oxygen from it, and algae cannot live without oxygen, and neither can we.

So, the cell walls rupture, and then when that happens, algae stop growing and reproducing, and then it, and then it just dies.

So, shocking the hell out of your pool will take care of any algae problem.

However, depending on the size of the problem, you may need to double, or even triple-shock your pool.

But at the end of the process, the algae will be dead and you’ll be able to vacuum all of that alga, that dead alga, out of your pool.

more in-depth tutorials on literally how to do this.

The best way to fight algae is to keep it from coming and to keep it from forming in the first place.

To do that, you need to keep your chlorine level at three parts per million at all times.

And if you use another sanitizer, the same thing.

Bromine pools keep that level between three parts per million and five parts per million, and for biguanide or baquacil pools, you wanna keep the level between 30 parts per million and 50 parts per million to keep algae at bay.

Proper sanitizers are only half the weapon.

You need to keep your pool’s pH between 7.4 and 7.6 for the algae-fighting powers to really be effective, and by the way, if you go swimming or you take toys into a natural body of water like a lake, or the ocean, you wanna make sure that you sanitize everything before you put it back into your pool, because algae are notorious for hitching rides.

On swimsuits and pool toys, and just because you can’t see it doesn’t mean it doesn’t exist.

Ominous, but true.

All that said, I do recommend using algaecide for specific purposes like closing your pool.

And when you close your pool, adding some algaecide to the water can help keep you from finding a nasty surprise in your pool when you open it back up next season.

And algaecide is a good backup solution when you don’t have enough chlorine or sanitizer in your water to keep the algae away.

If you wanna use algaecide as a backup, I recommend avoiding copper-based algaecides and instead look for polyquat algaecides.

If you see a bottle labeled “algaecide 60,” get that.
