There are over 400 kinds of algae that can develop in your swimming pool! That sounds pretty depressing doesn’t it? So how do you tell what the best algaecides for your pool are? The good thing is that they all fit into 3 types or colors.
The most common type of algae for most pools. Green algae can grow on the walls but it most commonly grows in the water itself making the pool look green.
Before you attempt to kill green algae you should make sure your pool filter is clean and your chemicals levels are balanced. Grab a good Test Kit and verify. The chlorine levels will need to be raised (shocked) to a very high level in combination with the use of a good algaecide to kill most green algae.
How easy it is to kill green algae usually depends on how long the algae has been in the pool. If it has only been there for a week or two you should not have much trouble killing it. If it has been there for a month or longer you may need to take more aggressive actions including draining and refilling your pool (not above ground pools or any inground pool during times with high ground water levels). You may need to contact me with specifics before you proceed so you don’t waste time or money. Please use the contact form on this website.
Yellow algae is also known as Mustard Algae. Yellow algae is yellow in color and only grows on the walls of the pool. It usually starts on the shady side of the pool but will quickly spread to the entire pool. It is also easily identified because it brushes off easily from the pool walls but will return if allowed in just a few days. This is the algae that most pool service companies deal with because green algae is usually kept to a minimum with regular maintenance. Yellow algae on the other hand will grow with normal amounts of chlorine and proper maintenance. Luckily we can still kill it with a good algaecide.
Yellow Algae also requires a high chlorine level and everything else to be balanced with a good Test Kit.
Shock the pool. Add one of the algaecides below following the directions on the label.
This algae can come back after killing it so keep your eye out for the formation of new yellow algae for a few weeks. If you see any repeat the shock and algaecide. You might choose to change the algaecide to the one used for green algae instead of the same algaecide you just used. This is because the algaecides work differently and you have already weakened the algae. Change the algaecide and you will most likely kill all remaining algae. It’s what I do.
This pain in the rear grows like a root in the pitted or rough areas of your swimming pool. They grow in small spots not larger than the size of dime but they can be numerous. The reason why I have so much disdain for them is because they grow a protective head over the root of the algae. In order to kill this algae you need to scrape off the head of each spot. This algae will spread if left unattended. I have seen pools with black algae everywhere! What a cleanup those were requiring lots of scrubbing and two or three algaecides. Luckily most pools only have a few spots.
First buy a quality Stainless Steel Brush. The trick here is to buy a brush that is not too wide. This way you can put more pressure on each spot with less effort. Brush every black algae spot and then shock the pool. A few hours after shocking the pool you can add a copper algaecide. Copper algaecides are great at killing black algae roots after the head is removed. You should be careful not to add too much copper algaecide (follow label directions) because copper can stain the pool walls if used too often or if too much is added.
Well, there’s talk of drought again this year, that means that water restrictions will surely follow. Here are a two ways you can minimize the evaporation on your pool. Either option should reduce your water evaporation by at least half.
Use a solar blanket or solar rings on your pool. Solar blankets warm the pool water and dramatically reduce evaporation. You purchase the solar blanket by length and width. The cover lies on the water directly. The cover can be cut to match the shape of your pool with scissors. Some people choose to cut the cover in half width wise to make removal and storage of the cover easier. A solar reel can also be used to roll the cover on and off the pool. If you are storing the cover in the sun folded up, you will need to cover the cover with a tarp or it will melt to itself. The best place to store the cover when not in use is in the shade. The average temperature gain in one week is 10-15 degrees. Please remember that any pool cover has a high drowning risk. Please be very mindful or avoid pool covers completely with children. Even teenagers are at risk when messing around under or jumping onto any pool cover.
Liquid solar blankets are easy to use and they work. The liquid cover needs to be added once per week for maximum effectiveness. I have found adding the product once every other week works well too. This product is a liquid that you add to the skimmer or top of the pool when the pump is running. The liquid spreads out and forms a layer only one molecule thick that reduces evaporation and retains heat that you would normally lose each night. The average temperature gain in one week is about 5-10 degrees. The product is biodegradable, eco-friendly, and safe to swim in. The dose is about 4oz. per 20,000 gallons of pool water per week.
Either product can be purchased at a pool store or through Just Right Pool Service directly. Please use this form when ordering. These options are optional of course. You can also email your order to firstname.lastname@example.org
15 X 30 Solar Cover = $135.00

20 X 40 Solar Cover = $205.00
Please circle the size of cover you would like us to deliver.
Solar Covers have a 6 year warranty. The first year is a full warranty and the rest is prorated. It only covers manufactures defects or issues with materials or workmanship. It does not cover the bubbles popping from sun and chlorine exposure. The average solar cover lasts a maximum of 3 seasons (FYI). Just being honest.
Cover Free is the liquid solar blanket mentioned above.
1 Quart of Cover Free = $35.00 plus tax
Weekly or Bi-Weekly additions of Cover Free = $5.00 per 4oz. dose (Please indicate frequency)
We can add this product for you at your desired dose/frequency if you indicate what you would like us to do. We can also deliver a quart container for you to add when you like. (Current customers only)
Green algae are the type of algae you see in the water itself. The water itself has a green color to it. If your water is turning cloudy, chances are you are about to have green algae in your pool. If you have cloudy water, shock your pool with chlorine at the rate of one gallon or one pound granular chlorine per 10,000 gallons of pool water and run the pool pump for up to 24 hours. If the pool has already turned green an algaecide will be needed in addition to the same shock treatment mentioned above. Simply add the chlorine as mentioned and immediately add one quart of “algaecide 60” per 20,000 gallons of pool water. Run the pump for 24 hours and re-test the chlorine level. Add more chlorine and run the pump longer if needed. Make sure the filter pressure stays within range. If the starting clean pressure of your filter is 10 lbs. then you should clean the filter when it goes up 8-10 lbs. above that. So clean this filter when it hits 18-20 lbs. Brushing the pool may be needed if you notice algae forming on the walls and floor of the pool. Algae that form to the walls grow a protective layer that makes it difficult to kill without brushing it away from the wall. The algaecide used for green algae is “algaecide 60”.
