can you use bleach in pool to clean the water?

Yes, you can use bleach in the spa, but there are a few precautions you must take first. You must make sure that you are only using regular bleach, not something with whiteners & brighteners, lemon scented, all-fabric, color-safe, etc. Straight Sodium Hypochlorite. Next, you still need to use something in the water to maintain a regular sanitizer level. The bleach works great as a shock, but it dissapates rather rapidly (which is why it's a great shock). Also, you need to test the spa water to make certain that the chlorine level has dropped down to a normal level before using the spa. Previous comments by others concerning no sanitization from bleach, bleach leaving a bad smell, only 3% strength, certain early equipment failure due to bleach use,and the need to rinse everything in the spa if you have ever used bleach are alarmist, unfounded and inaccurate. By the way, Clorox and others are generally around 5 1/2% strength, though the strength gradually depletes as it sits on the shelf, especially in a warm area. The comments previously posted concerning the corrosiveness of bleach and the hazards of mixing it with other chemicals are true, however they are also true about dry chlorine, bromine and pH reducer. Standard precautions prevail, including:

1. Never mix chemicals together in concentration, even two different types of chlorine. If you do, the results can be dangerous or deadly. Using different chemicals in your pool or spa, however, is fine because they have been fully diluted at that point. 2. Never handle concentrated chemicals with your bare hands, wash your hands after use, and only use in a well ventilated area.
