Why do you get heavy algae growth in your pool a day or two after using algaecide?

I just had a similar problem so I'll tell you what cleared mine up. I wasn't using enough Algaecide in my pool to correct the problem. I have about 32,000 gallons and the pool company recommended a quart and a half of an algaecide with 7% copper. I found mine at Walmart and it only had 3% copper, but it worked fine. Some of the products do not contain copper, they informed me, and copper is a necessary ingredient to kill the algae. Pour it in and let it sit overnight. Then vaccumm to WASTE the walls and bottom. The algae is so fine that it will remain in your filter and keep flowing back to your pool if you vac the pool in the normal way. The Copper ingredient bonds to the algae for removal. After the pool is clean, add a few ounces of the algaecide each week. I need to add about 6 oz. Let us know if this works for you.

Why might heavy lorries need eight rear wheels?
In a heavy truck, each wheel has to support large road and the pressure on the road due to each wheel is large. Since, pressure = force/area Using of extra wheels reduces the pressure on road due to each wheel. This prevents the wheel from causing damage to the road as well as sinking into soft ground. This is why, extra wheels are used in heavy vehicles.

How do you get several layers of paint off an old milk can?
Try using paint stripper that is sold in Lowe's or Home Depot. You also may need to resort to heavy duty sandpaper with a lot of effort.
Can algae prepare their own food?
Yes. Cut off the oxygen supply using an algaecide. It will die. Let particle sellte or use flock. Vacuum to waste and then use an algaecide on a regular basis.
Do you have more algae when using baquacil vs chlorine?
No. Actually it is more common to acquire algae in a Chlorine pool. The Baquacil Performance Algaecide is the strongest algaecide they make and very effective against killing algae. Maintaining the Oxidizer and Sanitizer readings do a great job of preventing algae where with a CL pool, in hot temps as soon as the CL reading drops below 1 the pool starts to turn green and the floors and walls feel slimy.
Can you kill algae by just using algaecide?
Actually, algaecide does not do the actual killing of the algae. It strips the cell walls of the algae and allows the chlorine (hypochlorus acid) to do its job. So algaecide works great as a preventative since it makes the algae much more vulnerable to the chlorine. I typically add 4-6 ounces of Polyquat algaecide per week as a preventative. A side benefit of Polyquat is that it also acts as somewhat of a clarifier.
If you put algaecide directly into swimming pool without mixing in a bucket of water first will it eat the paint away?
You don't have to mix the algaecide in a bucket of water, you can put it directly in the pool. I use Polyquat 60 that comes in quart bottles and add about 4-6 ounces per week. Just walk along the edge of the pool and pour it at the edge while walking. No algaecide will "eat the paint". It's not acid. In fact, all the algaecide does is strip the cell walls of the algae and make it more susceptible to the chlorine. It's the chlorine that kills the algae. However, one algaecide with a side effect of staining is Copper. It's a very effective algaecide, and it's safe - but it will stain concrete pools if it's used in a high enough concentration. And Copper can stain blonde hair as well. That's why I don't recommend using it. The preferred algaecide is Polyquat 60.
Does using algaecide work in garden pools?
It has always worked for me.
What is the best way to get your pool ready for the summer after the water has turned green?
Answer Green water to clear waterStart out by putting your filter on recirculate, do not filter. By a bottle of drop-out or floc. Add algaecide 30% to kill algae growth in the water. Adjust chlorine level to 1.5-2.0 and pH level to 7.5-8.0 for best results. Add floc or drop-out as instructed on the bottle to the pool water. Recirculate for 2 hours, then shut off pump for 12 to 24 hours. Vacuum debris at bottom of pool to waste. Adjust pool water height and check and adjust chlorine and pH levels. Also add algaecide 10% to pool to kill algae. If possible, also check alkalinity, hardness, and calcium levels. It would not hurt to clean the sand in the filter if you had started filtering the water before treating the algae growth. Patches of dead algae will appear at the bottom of the pool even after using the floc as it will still be in the water for several days. It will not harm you. Just vacuum debris to waste. Do not over treat the pool as this will cause cloudy water and delay its use.
Is it safe to swim after using algaecide treatments?
Its never done me any harm. However follow the directions on the container of the algaecide, if it tels you not to swim in the water for a period of time after treatment I would head their advice.
Will algae grow in a dark cool place?
Most microalgae grow through photosynthesis - by converting sunlight, CO2 and a few nutrients, including nitrogen and phosphorous, into material known as biomass This is called "autotrophic" growth. Other algae can grow in the dark using sugar or starch (called "heterotrophic" growth), or even combine both growth modes (called "mixotrophic" growth).
Grey sludge in water?
It sounds like you have an algae problem. Shock the pool and toss in a dose of algaecide. Take a sample of the water along to your pool shop and get it tested while you are getting the algaecide.
How much algaecide do you put in a 24 foot round pool when closing for the winter?
Assuming that your pool is 24 Round 52" Walls, Roughly 14,435 Gallons. Amount to be used will vary depending on the algaecide used. We normally recommend refering to the label of the algaecide you are using. We use Blue Wave Halt50 Algaecide with our winter closing chemical packages which recommends using 5oz per 10,000 gallons for booster dose. Follow this link for a great deal on a blue wave winterizing kit. http://www.royalswimmingpools.com/chemicals.htm#winterchems
What is the cause of green algae in pool?
Algae are a very simple type of plant, and like all plants they need water, food, and sunlight. There are different types, the most common being one of the varieties of green, but there is also yellow "mustard" algae, and the dreaded "black" algae which is hard to get rid of. Chlorine, Bromine, or an alternative like Baquacil is added to a pool to make it a hostile environment for algae and bacteria. If the chemical composition of the water is kept properly, algae shouldn't be able to grow in a pool. However, if the chemical level drops too far, algae can grow. They feed on phosphates and other trace chemicals in the water, and use the energy from sunlight to "power" their food-making process. One way that algae can get a "jump-start" is if there is organic debris in the pool like leaves, grass clippings, flower petals, etc. This organic debris is a prime source of fresh algae spores, and it will also react with the chlorine or other purifying chemical in the water, in effect using it up, causing the chemical levels to drop. To avoid this double-whammy, daily get organic debris out of the pool and skimmer baskets. If you have an algae problem in your pool, see your local pool store for chemicals to "shock" the pool by boosting the chlorine content briefly, an algaecide for the specific type of algae you have, and a treatment to remove the phosphates from the water to prevent future algae growth.

Why are chemical fertilizers harmful if they get in water?
Some chemicals are toxic at elevated levels (such as ammonia) and can cause mortality to fish populations, the majority are not at levels that increase mortality but they do encourage the growth of algae and other plant growth in the water. When the algae dies it decomposes using up the oxygen in the water - killing the fish. This process is called eutrophication (enriching) of the water ecosystem.
