I think I am dealing with black algae. It is stuck to the bottom of my pool. I have gotten a little lazy with testing my water and have just been adding some bleach when the the water wasn't sparkling as much as I thought it should be!!!
I have tested my water today and here are my results:
FC - 0
CC - 0
pH - 7.8
TA - 140
CH - 160
CYA - 25 (It was down to about 10-20 and I added a little bit of stabilizer to get it back up to at least 30)
Some of the black spots are REALLY stuck. I am brushing the bottom with a broom and still cannot get some of them loose. Is the answer still to shock and that is all??? Will that kill the algae and then I will be able to get it loose???? I cannot believe that my pool is NOT green!! It is not crystal clear today but it is no where near cloudy. The Pool Calculator told me the shock level is 12 so I will be adding 3 jugs of bleach. (182 oz jugs)
Our motor was really LOUD (it was going bad) so we had to replace it. Second problem: this new motor is a Waterway Eco-Kleer 1.5 hp. Ever since we got it the vacuum cleaner is just not doing the job it did with the old Hayward!!! You would think it would be doing a LOT better but barely moves around and won't hardly vacuum anything!! I have tried adjusting the cleaner but to no avail. This cleaner was purchased last year! It is a Kontiki Barracuda.
Any suggestions??? I run my filter 24/7. It is a sand filter but now has Zeolite will need to be changed next year.
I also need to get a new cover. We have LOTS of trees so therefore we have LOTS of leaves!!! Our last cover was mesh but it only lasted 2 years! Is that average????
