OK guys. I am changing this portion of my pool care to this thread as it no longer has to do with the electrical usage of my pump.
I tested my water for the first time and I got:
OK guys. I am ready to get serious about getting rid of this yellow algae as the weather in houston is warming up.
I used my test kit and here are my numbers. How bad am I?
Free Chlorine = 2.4
Combined Chlorine = .6
-in the book table to raise PH it says if your base demand test took 10 drops for a 20,000 gallon pool to use 6.4 pounds of soda ash. My pool is 25,000 gallons and took 12 drops.
My alkalinity is 120
My calcium is 870
My cyanuric acid I couldn't even read because the water got too cloudy before I got to the numbers on the side of the tester. at the 1.8 fill line I couldn't see the dot. at the 4.5 fill line the reading was 80. Not sure what this means.
I tested my cyanuric acid with half tap water and half pool water and it was still over 100. My Taylor tester only goes to 100.
I am currently draining my pool. I think I am just going to drain it all, unless for some reason I shouldn't.
I have heard of people doing an "acid wash" on the pool, before filling it. I haven't done research on that yet. Just wondering what the thoughts are on doing this before filling it.
Also, I have places in my plaster where the white is gone and you can see the darker material underneath. I don't know if this was from having the cyanuric acid level so high and brushing it. I know during regular brushing that I would see whitish powder come off in the water. You can see the bare spots in the pictures attached. Is there any reason I should be concerned about these areas where the white plaster is gone? besides cosmetic reasons. Do I need to get some plaster guy to fix this before I fill it up. I don't think the pool has any links. Here is a picture of my pool from the winter, here are two pictures of what it looks like mostly drained. I brushed it pretty good yesterday, that is why you can kind of see algae streaks on the walls.
