Algae and Phycology
Algae is a group of aquatic plants. They are considered simple due to the fact that they do not grow into distinct parts, like land plants. Seaweed is a type of algae. Phycology is the study of algae.

Click on the link to your right for algae info, if the question is about algae in the pool read below: Algae are tiny microscopic plants that enter your pool by rain, wind and fill water. If allowed to grow unchecked, your water will quickly become unusable. One ounce of water can contain millions of algae cells before they are visible. They can clog filters and reduce water circulation and the effectiveness of pool chemicals. The main types of pool algae are: Green Algae: The most common type of algae. It
Black Algae presents in 1 to 3cm black (or dark blue green) spots, It forms in a layers. the first layer may be killed by chlorine but protects further layers from destruction. This form of algae is slow growing and hardy. It is extremely chlorine resistant. to treat Black algae. Turn of the pump,Brush the algae spots thoroughly with a hard brush. then use chlorine tablets to treat the algae spots individually (this is not recommended for vinyl pools). Pour a concentrated all purpose algaecide on the algae spots. Leave it overnight. Restore water circulation, brush dead algae and vacuum it to waste. You may have to repeat the process .when you are finished, check the water balance shock the pool and make sure that you keep the chlorine up to it to help prevent further out breaks.
If the pink-purple algae keeps returning after shock treatments and algaecide, it may be resistant to those chemicals. To eradicate the algae, you may need to try a different type of algaecide specially formulated for pink algae, scrub the affected areas, and ensure proper circulation and filtration in the pool. Additionally, ensuring that the pool water is balanced and properly sanitized can help prevent the algae from returning.
UV sanitizers are effective at neutralizing bacteria, viruses, and some algae by breaking down their DNA. However, they may not be as effective against algae that is already established in the pool. Regular brushing and proper circulation are essential to prevent algae growth in hard-to-reach areas that UV light may not reach effectively.
Answer
algae grows naturally in water , try water and sunlight
Algae is found where the capacity of water and sunlight is more.. because it helps algae for photosynthesis. ....
Algae is also the photo synthetic plant..
How can you remove black algae stains from the floor in the deep end of a vinyl lined inground pool?
Black algae is very hard to get rid of You need to get down there with something an scrub the surface of the algae. this will damage it so that algaecides will be able to penetrate it Hit the pool with a suitable algaecide you will be able to get this at your pool shop and also try putting some dry chlorine in a sock and place it directly on the worst affected areas, leave it for a while and see what happens.
Why would there be brown algae on the bottom of a gunite pool and how do you get rid of it?
Algae spores float around in the air and can hit your pool at any time You can fix it by 1 shocking the pool and scrubbing the walls and floor of the pool if this doesn't clear it up just get an algaecide from your pool shop. When you vacuum the dead algae out of the pool it would be a good idea to vacuum it to waste to reduce the risk of reinfecting the pool.
There is no such thing as actual black algae. It is just a name given to crystallized green algae. Green algae that can not flourish will die and crystallize and try to grow again and again in the same spot forming those black buds. Usually you will get black algae from keeping a constant level of chlorine say 3 to 5 ppm's and not shocking (Raising the chlorine level over 10 ppm's) the pool often enough.
shocking will not get rid of algae,algae feeds on phosphates so you'll have to get your phosphate level down to zero using a product a pool store sells to control this.good luck.
Phosphates are only a big factor in Salt Pools, The areas with growth are not getting circulation to refresh the active chlorine. Or you are not shocking properly, If you are shocking with a chlorine base product you have to bring your chlorine levels up 10 times above current levels if you miss and only go 9.5 times is all it does is add more chloramines to your pool creating even a worse problem. I suggest using a Non Chlorine shock with it you add 1 lb for 10,000 and it always works without a bunch of calculations, and if you use to little it just works a little less plus you can swim in 20 Minutes.

Cleaning the filter helps.

What do you do if your pool has green algae and black algae spots?
If it is genuine 'black algae' it is very difficult to remove without emptying the pool and gouging the black algae out of the pool surface. Other algae can be removed by shocking the pool, filtering continuously and brushing walls while maintaining a good sanitizer level.
How do you get rid of algae growing in a toilet tank?
To remove algae from a toilet tank, you can start by turning off the water supply and flushing the toilet to lower the water level. Then, scrub the affected areas with a mixture of water and bleach or vinegar to kill the algae. Finally, let the solution sit for a while before flushing the toilet and turning the water supply back on.
Is a pool safe to swim in if patches of the plaster have turned bright blue?
If you are getting bright color patches on plaster hmmm, what is happening to the equipment also? You could have a chemical imbalance in your pool. Are you actually using a test kit to determine the readings of chlorine and pH? You may have reduced the life of the pool plaster and the equipment by many years. The stain may be caused by some water treatment that you have recently added or excess muriatic acid. However, muriatic acid usually produces a copper color to black stain on plaster. Be sure that you are not mistakingly using the muriatic acid instead of chlorine. Staining of sorts can be caused by a pump that is producing more GPM than the equipment can safely handle. Best bet is to hire a service tech for a one time evaluation of the color and plaster. He will test chemical parameters and advise. The nominal service charge will be well worth his professional advice. Someone will need to visually see the problem to determine a direction.

Is it safe to swim in a pool that has algae in it?
The Algae won't hurt you. But if the chlorine isn't killing the algae, then other microorganisms might be present also. But then, we grew up swimming in ponds and streams. After shocking the pool, the algae will take longer to dissipate, so I'd let the kids in 24 hours after shocking, even if the water is green.
No it is not!!!!!! We just returned from a trip to Mexico and stayed at a high end Resort. The pool was beautiful but on three of the days there we saw algae in the pool. It was cleaned out with manual sweeping and I suppose chlorinated or shocked. When we got home I had this horrible itching that was unbearable. Nothing could be seen on the skin, but it was so intense I could not not stand it even to sleep. The doctor prescribed a cortisone cream and said it had caused a severe dermatitis that may lie dormant and will be activated by heat, hot water, and WAS caused by the unsanitary conditions that let the bacteria and such grow in this pool. Do not swim in algae filled pools
Is there a mycologist in the house???
Greetings! I read this letter and replies quite closely as Oregons Willamette valley gets hit with the worst algae outbreak in recent memory .
This is the first I've heard of algae causing dermatitis related problems. I remember coming out of streams and ponds covered with it down in S.C. Perhaps a strain that won't survive this far north?
Allergic reaction I could understand. But those are immuno-specific and tied to the patient, not the organism present in the pool.
But I am a lot more inclined to cast the questioning eye toward the sparkling water and filtration of the pool.
The definitive answer is "it depends."
Europeans swim in pools that have algae on the walls, yet also have a high ORP (oxidation reduction potential- as measured in millivolts of conductivity).
The high ORP is usually due to the use of ozone, which kills viruses, bacteria and pathogens, and oxidizes bather waste (urea - sweat, urine & cosmetics - suntan lotion, hair gels, cream rinse, etc.). The short half life of the ozone does not allow the ozone to remain in the vessel (pool/spa) long enough to kill the algae. Thus their pools are sanitary & safe to swim in (no pathogens and sparkling clear), yet they have algae.
The reader who got sick probably swam in a pool which had bacteria, viruses, and algae due to poor water chemistry maintenance.
The best piece of advice that I can recommend... carry your own pool water test strips when you travel, and perform a test before swimming. I do this when ever I travel, and especially when using a public spa/hot tub.
2 rules to remember:
- 1: If your eyes burn after swimming, it's not due to TOO MUCH chlorine, it's from too little (chlorimines). (Or improper pool water pH).
- 2: If you smell "chlorine" when you approach the pool or spa, turn around & go golfing. What you smell are chloramines (chlorine that's combined with bather waste, aka. combined chlorine), and that is an indication that there is not enough chlorine in the pool!! A high level of chlorine in a pool (even as high as 10 ppm) barely has a smell. And yes 10 ppm is safe to swim in - only hyper-sensitive folks might itch and cheap fabrics may bleach/fade.
Remember: Most water chemistry problems, eye irritation complaints, and murky water are a result of too little chlorine!
If it's a public pool and it's green, I wouldn't dip my finger in it. If it's your private pool, then it depends, I am not going to repeat the valid points above..

What mechanoreceptors is function?
Mechanoreceptors are sensory receptors that respond to mechanical pressure or distortion. They are responsible for detecting sensations like touch, pressure, vibration, and proprioception. Examples of mechanoreceptors include Merkel cells, Meissner's corpuscles, Pacinian corpuscles, and hair cells in the inner ear.
found 1 meter below the surface on cloudy days. The study concluded that sunlight penetration was the main factor affecting the depth distribution of the algae.
What is yellow algae and how do you recognize it?
Yellow algae is as the description states yellowish in color. You can determine if you can see a yellow tint on the white or light surface of the plaster or vinyl. You can further determine algae by just brushing the yellow spots -- if it brushes off then it is most likely yellow algae. Mustard algae is similar but will be harder to brush off. The algae usually breeds on the shady side of the pool first then progresses to the rest of the pool depending on how long the pool has been neglected.

What is a human use for corella algae?
Corella algae can be used in human nutrition as a source of omega-3 fatty acids, which have been shown to have numerous health benefits. It can be used as a supplement in the form of capsules or as an ingredient in food products, such as smoothies or energy bars. Additionally, corella algae has potential applications in the cosmetic industry due to its high content of antioxidants and moisturizing properties.
Many deep sea fish eat glass squids, that includes angler fish, goblin sharks, and whales.
Diatoms are single celled algae and one of the most common types of phytoplankton. Because they undergo photosynthesis, they are considered autotrophs.
Can algae cause the surface of a pool to be rough?
Yes, if there is a lot of it floating on the surface. Take a look at a ditch or shallow pond anytime from midsummer to fall; sometimes the entire surface will be covered with a green slimy layer of algae up to an inch thick.
If your pool has had shock treatment to remove algae what could be another cause of a green pool?
It could still be yellow or mustard algae. Chlorine is not always the only antidote to an algae bloom. You must use an algaecide, as well. Copper- and silver-based varieties are effective. When the algae is dead and sinks to the bottom, it may appear grayish in color. Vacuum that out to waste. If the green stuff is only on the bottom and not forming on the ladder, skimmer parts, walls, etc., perhaps you don't have an algae problem. Perhaps you have a calcium problem. Does the greenish stuff "poof" and easily disperse when you disturb it with the vacuum head or a brush attachment? Is the water generally clear except for the ick at the bottom? If so, it could be calcium buildup. If you use a calcium-based chlorine product and have been doing so awhile, then it's quite possible your problem is calcium. You need to very carefully vacuum that precipitate out to waste, replace the water you ejected with fresh water, and switch to a non-calcium-based product. The answer above neglected to mention an important part of the pool - THE FILTER. Without the proper length of filter run time you will get nowhere in having a clear, quality pool.
We have had several problems w/our pool water and it seems that whenever we purchase ANY Bioguard products it clears it up right away. Bioguard has a website www.bioguard.com and you can locate a dealer near you. Their products are great for any problem. We are using their 3 step program to maintain our pool and it's simple and great and we have crystal clear water. Good Luck.
AnswerYou have this problem because you are trying to vacuum microscopic particles that are small enough to slip through the pool filter. What you want is a product that clarifies by causing the particles to clump together and sink. These larger clumps won't stir up so badly, and will be caught by the filter as well. Answeranother thing you can do is vacume your pool on the waste setting which will pump all small particles you pick up that are too small for your filter out of your pool forevcr. It takes longer though because you have to make sure you keep your water level up above the skimmer line if it is an in ground pool.How soon after shocking the pool is it safe to swim?
After shocking a pool, a person should wait at least 24 hours before going into the pool. This allows the chemicals from the shocking treatment to evaporate, therefore, making it safe for your skin.
