Everything you need to know about Pool Algae
How Can I Remove Algae From My Swimming Pool?
So you have got algae in your swimming pool. Now you need to get rid of it. Firstly you need to know from where it is getting into your swimming pool. There are several possibilities, including rain, wind, or people that are using the pool.
If the chemical level and circulation of your pool is poor, algae can then thrive and multiply in your pool. Initially, you may not be worried about how algae got into your pool, but more importantly, how you are now going to remove it from your pool. It is important to start treating it straight away, or it could end up being very expensive to rectify the problem.
When your pool is shut down for the winter if it is not checked regularly for clarity under the cover you can end up with really bad algae problems which can then adhere to the debris cover causing you a lot more problems to eradicate the algae.
Identify type of Algae
There are several different types of algae so it is important that you identify the type before starting treatment. Green algae is the most common type of algae and can be found on the walls and floor of the pool, which can make the surfaces slippery making it a hazard for users of the pool to slip on. The appearance of the pool water will have a greenish tinge to it and most likely have murky water causing poor visability.
Yellow/Mustard algae is a difficult algae to remove, as once you have it in your pool it is very easy to get it back again if not thoroughly treated for removal. It needs to be treated as early as possible to try and stop it spreading further into the pool. The most common place for it to adhere to is any shady parts of the pool.
Black algae is the most difficult to eradicate. It has green blue or black spots. It has a sticky type of deposit and the spots are small sometimes not that noticeable. Should you find this type of algae in your pool it will be very difficult to eradicate. One of the main problems are the roots of the algae it can get into the plaster or grouting, making it easier for the algae to multiply.

Maintenance Process Prior to Pool Algaecide
Manually clean the pool
Now to cure the problem. Firstly turn on your filter and pump on to run for 24 hours per day. Robotic pool cleaners are not ideally suited to clean off any algae. It is better to manually clean the pool directly to waste bypassing your filter so preventing recirculation of contaminated water, paying special attention to areas infected with algae.
Brush the pool walls
Use a nylon pool brush to clean the walls and floor of a vinyl pool, get as much of the algae off the walls and floor as possible. If the pool is concrete use a steel brush. Taking extra care in the corners and edges to eradicate all traces of algae. As you start to clean the water will go cloudy, so do the worst affected parts first while the visibility is better.
Test pool water
Using test strips or a pool tester check the pH levels of your pool water, which should read between 7.2 and 7.6 with an alkalinity of 80 to 120ppm, and calcium hardness of 200 to 400, that will ensure that the chemicals will work properly when added to your pool. If you have low or high alkalinity it will stop the pool shock working.
The harder to kill algae require a much more aggressive dose of shock. If you don’t normally use chlorine shock, it is still the best way to solve the problem. Follow the package instructions to find the correct amount to dose your pool then you will need to multiply that by x 2 for Green Algae. Multiply that by 3 for Yellow or Dark Green Algae, Multiply that by 4 for Black Algae.
You now need to vacuum the pool to waste. If you have to use your filter to vacuum you need to ensure that the filter valve is set to waste, this applies to sand filters only. (During this process make sure that there is sufficient water in the pool to run the filter). Then this will bypass the filter and push what you are vacuuming directly from the pool, as the last thing you need is any particles getting back into the pool. At this stage you should use a flocculent to help gather any remaining floating algae particles which can then be vacuumed to waste. All this will help the process of eliminating algae.
Allow the filter to run continuously for 24 hours checking after 12 hours to see if there is any significant improvement. If not add a second dose of shock keep the filter running and check again after 12 hours. If you have effectively killed the algae your water will go a cloudy blue.
Pool Algaecide chemical is good for treating pools that have gone green over the winter.
This product kills the algae and small organism’s that thrive in damp conditions. Algaecides work in conjunction with chlorine, causing the algae cells to burst, thus killing the plant. Ammonia-based algaecides are very affective on green algae and metallic-based on black algae; the right amount of algaecide should not affect your pH balance too much.
AquaSplash Pool Algaecide Chemical Treatment
There are two types of Algaecide one being a Longlife Algaecide, and the other one is a standard algaecide. The standard algaecide is ideal for above ground pools and is also suitable for Inground pools. The longlife algaecide, however, is more suited to inground pools rather than above ground pools. To use algaecide, the water must be of good quality for it to work properly. Algaecides will not clear murky water or water with poor test results. Algaecide is intended for use to keep the pool sparkling clean.
