Green Water in Swimming Pool – What to Do?

green pool waterTaking care of a swimming pool is a lot of hard work. When you have green water in your swimming pool or even black and very, very dirty, you may be at a loss to know what to do. Luckily there are proven steps to taking care of this kind of problem. The best way to take care of this problem is to avoid it altogether to begin with by hiring a good pool Service Company to provide weekly pool service. When you take this precaution, you can avoid having a problem that gets out of control.

However, if it’s too late for that, and your pool is already a problem, there are a few steps you may want to take. First, use your leaf net to get any large debris out of the pool. Be advised that when you do this, you’ll stir up the water, and it may seem that your problem is even worse than before. Don’t panic! Just wait until the water settles. When you can see the bottom of the pool, if the waste and debris is not too excessive, you can vacuum the pool. If there is a tremendous amount of debris on the bottom of the pool you’ll need to take other measures. Vacuuming will clog your filtration system and your skimmer under the circumstances and may even damage underground water lines.

Once you’ve gotten all of the large debris out of your pool, you’ll want to check the PH levels and the alkalinity levels. Be sure they are in the appropriate ranges before doing anything else. If they aren’t you will simply be wasting time, effort and chemicals.

How to balance swimming pool ph levels

If your PH levels and total alkalinity are within proper ranges, you can give your swimming pool a shock treatment. You can purchase shock treatment in either liquid or powder form. Be sure to check with the local swimming pool service to find out which is recommended in your area. Delivering a shock treatment consists of super chlorinating and your pool water to destroy any and all germs and algae. For a very, very dirty pool, you’ll need a very strong shock treatment, and it may take several days for the water to clear. Don’t be afraid of over shocking. This isn’t a problem. Simply apply good strong shock treatment to clear the debris and cloudiness in your pool.

Once you’ve done a thorough shock treatment you should begin running your filter continuously. Clean it two or three times every day to get results more quickly.  Or check our pool filter cleaning page.  If your water is green, black and/or filled with debris, it will naturally clog your filter quickly, so you may need to backwash your filter very often until your pool water is clear. It’s better to backwash your pool filter more often than necessary than to not backwash enough.

If you have a diatomaceous earth (DE) filter you will want to add fresh and DE to the skimmer that is nearest to the filter after you backwash. Do this every time you backwash. Even though this may seem like a lot of work, it’s worth it because your DE filter will clean your pool more quickly and completely than any other kind.

After your water is cleaner, you may see that there’s quite a bit of debris in the water and on the floor of your pool. If this is the case, again you want to remove as much trash and debris as you can with your net. Then you can vacuum pool. If there’s just too much trash for you to handle, you must have a pool maintenance company come in and take care of it for you to avoid further complications and problems.

Be aware that you may spend several days following all of these instructions and struggling to clean your pool without success. There are a number of reasons why this might happen. One of the most common is that your filtration system is simply not working correctly. If this is the case, you must consult with a swimming pool repair service to have your entire system checked out and any needed repairs or equipment replacements taken care of.

A local pool service company may advise you that the best thing to do is simply drain the pool and start over again. This could be a very expensive proposition, and after you have spent several days attempting to deal with your pool problem unsuccessfully on your own, you might find it unbearably frustrating. Nonetheless, if your water is very badly contaminated there’s nothing else to do. After you have entirely fresh water in your pool, it’s advisable to continue with weekly pool service from a local pool service professional to prevent this kind of situation happening again.
