Pool water looks green.?
Question:Ok I know this has been asked before but this is a little different. A week ago a green towel fell into pool and sat for a few days before we noticed. Then I noticed some green spots in pool, and figured since the towel was now faded it was the dye. Swept, pool was fine, but now pool is all green (cant see bottom) after husband went in to sweep some green spots today. We shocked it and already put algaecide in our frogger as well as have clorine tablets in frogger now. The weird thing is the water isnt really green (when I scooped some out it was crystal clear.) So why is my pool look green? I doubt it is algae as it is not slimy, and like I said we used algaecide. and shock? This has never happened before. Thanks
Answers:
OK here is what you do ! add 1 lb of sodium dichlor per 10,000 gallons of water once a week under normal conditions. but since your pool is green you need a jump start so add 4 to 5 lbs of sodium dichlor and then run your pool 24 hrs a day until water clears up. there is no need to brush pool until algae is dead, you are just moving the algae around. forget about the algaecides you are wasting money.
the dye from the towel stuck to the surfaces?
Check the PH. If this is way out alge will continue to grow even in a high clorine environment.
Sure sounds like Algae, Try brushing the bottom and see if it clouds up if so its algae
There is no need to guess. http://appliancequickfix.com/ has
one great page on pool water and no, its not the towel. It lost its color because its now bleached. Its algae, take 5 minutes and see how to deal properly with it.
Sorry it's not the towel it's algae. Algae doesn't always present itself as slime, and I've seen pools turn completely clear after the algae is vacuumed off the the pool surfaces. After you shocked the water did you test the chlorine level? If a pool is green you can shock it and the residual chlorine level will drop down to 0 after it has killed all it can. You have to keep the level up until there is no more biological material (algae, bacteria) present. Then use the algaecide. It's also a bad idea to use sodium diclor if you already have a good cyanaric acid level as it can cause overstabalization. Running the pump 24 hours a day is a good idea but you can brush the pool before you shock it as long as you use enough chorine to kill the algae. For shock use any brand of calcium hypochlorite with at least 67% available chlorine. If it's still green I would add an initial dose of five poundS of shock. Check the residual free chlorine level after 24 hours of circulation. If it dropped back down to 0 double the amount of chlorine. Repeat the same process, if it has a residual level, adjust until it is over 5 ppm, keep it over 5 for about a week. Keep tabs in the whole time. Once the pool is cleaned up add the algaecide. Algaecide is not a waste of money. It removes the phosphates which algae feed upon. They also feed upon nitrates which Algaecide does not remove, which is why you will still have algae no matter what in the summer. With algaecide you cut out one food source... it helps trust me.
Just to get you thinking about the possibility of the towel dye... chlorine has the same ingredient as bleach... hypochlorous acid. It destroy organic material like dye. This is why it does a good job a keeping things white... even if you don't want them to be. The dye is not leached out into the water it is oxidized and removed as nitrogen gas or filtered out... Even if the dye is not removed it would just turn the water cloudy and colorless. Anyways yeah it's not the towel I promise.
