Clear Up Swimming Pool Algae and Cloudy Swimming Pool Water. Bad Pool Water Maintenance Is The First Sign Of Green Swimming Pool Water.
Do you know what's not fun? When you walk outside and see green swimming pool water, especially when it’s a major weekend and you have all of your friends over. Right? Not fun at all.
So where do these nasty algae spores come from? Algae spores are constantly entering the pool through a variety of avenues. Wind, rain, and other contaminants contribute to the problem. Algae is a solid physical living organism that can grow and reproduce very quickly. It grows so fast it can double in size in less than 24 hours, especially when conditions are right such as warm sunny days. A green pool can certainly take over your life and bank account.
While there are many contributing factors for swimming pool algae blooms, the main reasons are:

Take Precautions First
When dealing with pool chemicals there are a few things to remember: Always take the proper precaution in dealing with these types of pool chemicals and read the manufacture’s labels. Use heavy-duty rubber gloves and goggles. Keep pool chlorine and other pool chemicals out of reach of children and pets.
Know Your Chemical Readings
It's virtually impossible to know how to clear up your pool with the chemical numbers. Ranges and colors don't work. This is why I use and recommend the Taylor FAS-DPD K-2006. Test strips are easy to use but they're not nearly as accurate as a good pool water test kit. The TF-100 is also recommended. If you live in a place with high calcium fill water, you might want to use liquid chlorine (sodium hypochlorite). Many pool owners use bleach. It's simply slightly watered down pool chlorine. Be sure your pool pH, alkalinity, CYA (pool stabilizer), and calcium hardness are adjusted. Be careful when using Dichlor. The CYA can get out of hand quickly. For every 10 ppm of chlorine added with Dichlor, you'll raise the CYA by 9 ppm. Trichlor chlorine tablets are a great way to weekly dose your pool with chlorine but it does add CYA. For every 10 ppm of chlorine added with Trichlor tabs you'll raise the CYA by 6 ppm. Flocculants (flocculate), certain algaecides (other than PolyQuat 60), clarifiers, coagulants, phosphate removers, etc... only mask the problem of algae in pool water. You must know the chemical readings and how to read them.
Sweep It & Scoop It
You want to remove as much debris from the pool as possible, so grab your wide-mouth leaf and start scooping. The little blue skimmers are fine for some light work, but nothing beats a wide-mouth leaf rake. Make sure you have a soft nylon brush for your vinyl or fiberglass pool. NEVER use a wire brush on those kinds of pools. Wire brushes are ONLY for plaster/concrete pools. Brush the sides, steps, floor, and water line.
Shock It With Chlorine
Be sure to turn OFF your salt water chlorine generator before shocking the pool. Shock the pool with liquid chlorine up to 15 - 20 ppm and maintain a high chlorine level. You might need to add chlorine morning and night to achieve killing the swimming pool algae.
Keep The Filter Running
Run the filter 24/7 and clean or backwash your filter every 10 - 12 hours until the water clears.
Not all cloudy pool water and algae in swimming pools are the same. Green swampy water is a sign of algae. Clear emerald green water can be high metal content. You will approach them differently.
