You may be able to buy the CYA at Lowe's, Home Depot, or Walmart. It may be labeled as stabilizer or conditioner. Check the label. If the ingredients say cyanuric or isocynuric acid, it is the right stuff. If those place don't have it, your pool store will.
If you consistently sustain the high cl reading, it will kill the algae. But, you have to be diligent about it and stay on top of it. If you take a day off, then you lose ground. Brushing your pool will speed the process.
Watermom,
I got the CYA and started to put it in the pool. And I'm keeping the chlorine level high real high. I have some questions, I was trying to figure out the pipes that are going from the pool to the water pump and the filter. The guy that lives here, named them as such. PS, SS, those are the two pipes that going to the water pump and on the other side there is another pipe going to it as well that has PD.
I do have a jacuzzi as well I don't know if this will help, the guy that came and gave me the pool class couldn't figure it out either.
Might be helpful if we have pics. Send them to poolforum DOT pics AT gmail DOT com and reference the URL of this thread.
Watermom,
Yesterday I made the mistake of buying CYA that was liquid I forgot that I had to get granular CYA so I went and bought that today. Do I follow the instructions on the bucket or do I follow the instructions on putting some of the CYA in a sock and having it desolved by itself. The intructions tell me to disolve it in hot water and pour it in the skimmer. Is that what I should do?
Thank You,
Oscar
Since you are fighting algae and will be backwashing frequently most likely, you don't want to put it in the skimmer or else you'll just throw it out with the backwash water. Use the sock method.
Backwashing, Hmm I haven't been doing that? When should I do that? And am I supposed to change DE and all that when I backwash? See I told you i'm new at this. Don't really knwo what i should be doing.
Thank You,
Oscar
I'm assuming you have a DE filter. You should backwash it when your filter pressure rises 8-10 psi over the "clean" pressure, or when you notice reduced flow from your returns. The backwash process will wash the DE out, so you'll have to add more...I'll let the DE filter people advise you on how much DE to add.
