Algae is a natural part of any pool. But left unchecked, it can grow out of control and even clog your filter. Not to mention it can quickly turn your pool from a place of enjoyment to a place of disgust.
To keep your pool clean, you need to clean regularly with an algaecide. But you wonder: How much algaecide do I need to put in the pool?
It’s a good question. And it’s one that every pool owner sooner or later has to answer for themselves.
But if you’re doing some research and want to know how much algaecide to put in pool, I’ve got you covered.
This blog provides a detailed breakdown of what pool algaecide does. Also, we’ll provide a step-by-step guide on how to measure your algaecide dosage. For this and more, read on!
What is pool algaecide?
Algaecide is a chemical that kills or prevents algae growth for sparking pool. Did you know? Algaecide is also an effective treatment for pool foam.
How does it work?
Well, pool algaecide kills and prevents algae in two ways. First, it stops photosynthesis, hence depriving algae of food needed for growth. Second, it causes the algae cell walls to burst, hence killing them. Simply put algaecide interrupts vital life processes in algae.
How much algaecide to put in pool?
How much algaecide you need depends on many factors. These include pool type, pool size, type of algaecide, and the degree of algae growth. Still, we’ll outline the dosage that’s generally accepted by pool experts across the world.
Well, there are two types of algaecide treatment: initial treatment and maintenance treatment. Always, the dosage for initial treatment is more than that for maintenance treatment.
How much algaecide for 1000 gallon pool?
Well, for a 1,000-gallon pool, the dosage for initial treatment is 1.3 fluid ounces. For maintenance treatment, use 0.3 fluid ounces for every 1,000 gallons.
How to measure the capacity of your pool
The problem with pool treatment is that you may not know the exact capacity of your pool. In fact, most pool owners make the mistake of relying on guesswork.
Well, don’t all victim. After all, the wrong estimation might make you put too much algaecide than required, causing more harm than good.
To stay safe here’s an easy way to measure your pool capacity.
For rectangular or square pools, the formulas is:
L x W x D x 7.5 = Capacity in gallons
For elliptical or circular pools, the formula is:
L x W x D x 5.9 = Capacity in gallons
L= Length in feet
W= Width in feet
D= Depth in feet
Adding Algaecide to your pool
Before going further, we recommend using algaecide after every shock treatment. This way, it has a better chance to support chlorine and work its magic.
Also, ensure you wear protective gear when handling algaecides. So, have protective eyewear and clothing handy. These include goggles, face shields, and rubber gloves
Test the water balance and adjust the pH level to 7.2 - 7.6. Also, use a scale inhibitor if any metals are present.
Unpack and measure the recommended dosage of 1.3 fluid ounces per 1,000 gallons. Add it directly to the pool water along the edges while the pump and filter are operating
Wait for 24 hours. If any algae are present, vacuum your pool.
How long does it take for algaecide to work?
It should take about 24 hours for the algaecide to work. However, the time frame can vary
depending on different factors.
First is the type of product. Some algaecides start working in a few hours, while others may take
a day or two to start doing their job.
Also, the type of algae will determine how long it takes algaecide to work. Green algae are the
easiest to get rid of while black algae are the most difficult as they have a protective barrier
Plus, chlorine can also affect how quickly an algaecide works. This is because chlorine will kill
any algae that may have started growing before the algaecide is introduced.
Additional maintenance tips
- Add the algaecide weekly for maintenance treatment. Use the recommended maintenance dosage of 0.3 fluid ounces per 1,000 gallons.
- Always ensure water circulation systems (pump and filters) are active when adding algaecide.
- Apply more often in case of heavy rains or frequent backwashing
How long after adding algaecide should I use the pool?
The pool will take some time to clear after algaecide treatment. So, when is the safe time to go for a swim?
How long you’ll wait depends on the severity of the algae attack. For mild cases or maintenance treatment, you only have to wait 15 minutes. For severe cases, however, it can take hours. But according to pool experts, the best time to wait is 30 minutes.
NB: Most algaecide treatments are perfectly safe to swim with.
What if I add too much algaecide in my pool?
Too much algaecide leads to foamy pool water. However, be careful not to confuse it with air pockets in the filter. Besides foamy pool water, the presence of too much algaecide leads to eye and skin irritations.
So, how do I remedy the problem if I accidentally add too much algaecide?
The good news is that you can use everyday kitchen ingredients. To do this, mix1 part baking soda and 2 parts vinegar with 9 parts water. This will dissolve the foaming agents in the pool.
FAQs About Algaecide for pools
Is chlorine a good weapon against algae?
Algaecide, though specially formulated to kill algae, isn’t the only effective solution.
You can use chlorine too. In fact, it’s much more effective at getting the job done, even in extra slimy algae-infested pools. However, you’ll have to maintain a consistent balance of chlorine, bromine, and pH.
Can I use sodium bromide as an algaecide?
Sodium bromide isn’t an algaecide in itself. However, when mixed with granular chlorine, it makes an excellent catalyst for getting rid of algae. In fact, it works well in more severe cases of algae bloom, both green and yellow algae.
There’s nothing worse than seeing a scummy film all over the surface of your beloved swimming pool. It’s a tell-tale sign that your pool needs algaecide treatment.
But how much algaecide to put in the pool dictates how best you’ll address the problem. Too little, and it will be ineffective. Too much, and it will cause skin irritation and a foamy pool.
However, with this detailed guide, you can say goodbye to guesswork and algae blooms. But for even better results, we recommend that you be proactive in the fight against algae growth. Also, implement algaecide treatment consistently.
