K1KO247 on April 28, 2011 at 4:32 pm Question once u pour the pool first aid do I shut the pump off or I continue to run it NaturalChemistryTV on April 28, 2011 at 4:38 pm K1KO247 Let the pump run after adding First Aid. The filtration of the water is key during this part of the algae clean up process…just be sure that the chlorine level is not above 5 ppm when you add the First Aid. Good luck and let me know if you need any more help! Chris SB8976 on May 30, 2011 at 2:39 pm You skipped over how to fix a cloudy pool! 🙁 Kevin Prasad on July 15, 2011 at 12:02 am how do i fix cloudy blue water after i have tried: clarifier, shock, ph +, metal free, keep on cleaning filters? i really don’t wanna have to drain and refill the pool NaturalChemistryTV on July 15, 2011 at 7:03 pm @igotalife787 Assuming your water chemistry is in balance the cloudiness is most likely from dead algae remaining suspended in your water. Pool First Aid should fix this, it is a combination of a clarifier and enzyme blend that actually breaks down the dead organinc material. Or you can also use a clarifier, but beware not all clarifiers are created equally and usually you get what you pay for. Natural Chemistry’s Clear and Perfect is the most powerful clarifier on the market. Good luck! stargazer3335 on February 28, 2012 at 5:50 pm When I vacuum my pool the algae comes back in thru the jet, any suggestions as to why? Dauzq De on March 4, 2012 at 4:02 pm fantastic video thanks! maithai23 on March 16, 2012 at 4:24 pm this video was so helpful! it’s going to save me hundreds of dollars. Thanks! NaturalChemistryTV on March 16, 2012 at 6:47 pm @stargazer3335 It sounds like the small particles of dead algae are not being collected on the filter media. I would guess you have a sand filter, if this is the case you can use a pulp based filter aid. You can purchase a number of good filter aids from either local pool retail stores or online,it will top coat the filter media and make your filter able to grab smaller particles (the stuff that is returning to the pool). Please let me know if you need further assistance please let me know.
