They are on the right. --> Use pool shock. Double shock it to get rid of algae. Start using "No-Phos" or "Phos-Free". This eliminates the food for algae. Use an algacide to kill the existing algae. Brush all the surfaces of the pool every day to keep algae from latching onto the walls. Vacumn and backwash twice a week to get rid of the dead algae. Make sure your pH is correct so the chemicals can work properly. Once your water is clean, keep using the No Phos product every week. This has saved us hundreds of dollars in chemical use. I'm not sure what you mean by "the water is balanced", but if it means that your PH and Alkalinity levels are ok, then I would suggest making sure that the chlorine levels you're checking are for Free Chlorine, not Total Chlorine (there is a difference). If the Free Chlorine is fine, then as the first guy said, I would shock the pool. If your Free Chlorine dips below the normal levels, however, you should use chlorinating shock. That way the chlorine jumps up, and any chlorine tablets you add into the pool will keep the chlorine level high.
Once the algae is dead, brush the entire pool (including the walls, floor, and any stairs, ladders, lights, or other objects that are in the pool). Brushing the pool stops the algae from sticking to anything in the pool, and allows it to be picked up by your filter. After you brush the pool, run the pump, and clean the filter when necessary. You'll know the algae is dead when the pool stops being green - the green color is chlorophyll, which is the chemical that the algae uses to get energy using photosynthesis.
Check your Alkalinity and PH. Those need to be balanced (in recommended range for your pool type) first. If not, chlorine will have little affect, and it will be eaten up quickly. It's actually amazing how important it is to have a fairly balanced pool before shocking.
It could possibly tint your hair green. Your hair won't completely turn green, it will just be a little more visible when your standing in direct sunlight. Aside from that, chlorine damadges any hair, whether it was dyed or not. Wet your hair before you go swimming. If your hair is already wet, it will be less likely to absorb the chlorine.
No. From some parts of the world it is NEVER visible.
Sounds like you may have some problem with algae And you my need to add a stabilizer to help preserve the chlorine. Your best bet is to take a water sample from the pool to a pool shop where they can test to see if you have the balance right and tel you how to put it right if it isn't
You buy a little test kit, and adjust the chlorine as directed.
Do you mean that adding a little chlorine made the reading go from 0 to a higher level? You should shock your pool once a week with 1L of liquid chlorine per 10000L of water in your pool. You need to add enough chlorine to break apart the combine chlorine (the combination of chlorine and dirt which doesn't sanitize.) If you don't add enough at once, it will be used up and the chlorine reading will remain low.

Ultra violet has a little bit shorter than violet the one extreme of visible region and infra red has wavelength a little bit longer than red which is the other extreme of visible light.

No, just add a little more chlorine to keep the chlorine level up, since the sun breaks down chlorine quicker. Hatawa
The type of water that contains the lowest amount of chlorine is spring bottled water. Normally it contains no or little chlorine.
If you don't gauge your ears they are only slightly visible. If you gauge them then they become much more visible.
