My pool looks clean, I sanitize with 12% chlorine weekly 1.5 gallons, but I still get some green on my stairs. Do I need to brush more often? add more chlorine? Its not bather load as we haven't used the pool at all as we have been away. Not a lot of trees either. Thanks Dave
What is your CYA level and are you keeping your chlorine in range per the Best Guess Chlorine Chart?
thanks Wmom I did not check I will now
just got back Watermom, No chlorine at all 3 dippers and nothing. Today is the day I normally sanitize. I put in 2 gallons and tomorrow I will check and get back. Again thanks
How often are you testing and adding chlorine. Sounds like not often enough.
Just once a week. Maybe I will test every other day. What do you think? Thx Dave
With testing and adding chlorine only once per week, it is no wonder you are getting algae. We recommend testing chlorine and pH daily. Especially while you are learning how your pool behaves. Doesn't take more than 5 minutes tops.
ok ...understood will test daily till further notice. Thanks Watermom
ok Watermom, I'm at 2.1 on my chlorine and 40 on stab. or cya. Im afraid all my ch burned off and if I add more it will go also, until I do something about stabilization
A CYA of 40 is a good reading. We typically recommend 40-50 for most pools. If you want to bump it up to 50, that would be fine.
Since you dropped below the recommended minimum of 3ppm and you have a little algae on the stairs, then you should shock your pool to kill it and clear it up. Also, brush the pool especially where you see the algae. Run your pump 24/7 while you are clearing it up.
Once you get the green cleared up, then the testing process for your pool will be this. When you test your chlorine each evening, add enough to take your chlorine level back up to around 6ppm. For reference, using a quart of 12% will add about 2.3ppm of chlorine to your pool. By the next evening, if you find that your chlorine level has dipped below 3ppm, then take it up to 7ppm. You want to take it high enough that you never drop below 3ppm by the following evening.
Hope this helps.
