algae help

[cschnurr]

The amount of bleach you added should get you around 15ppm. I would measure with a test kit to find out where you are and not rely on strips.

You now need to monitor Cl 3 times a day keeping it at this level. As the Cl eats the algae, Cl is consumed and Cl level will drop until the algae is gone. You can tell when this has happened when there is no overnight drop in Cl. I maintain Cl at shock levels until I get 2 nights without an overnight drop.

You need to turn your SWG off to make sure it's not adding Cl overnight. I turn the SWG off and rely on only bleach while I'm shocking.

Whether or not your SWG is working I can't tell you, but the SWG cell has a life (#hrs of operation x %Output) and running it at superchlorinate is the same as 100% output. I use liquid Cl during shock so as not to use up my cell life and I don't know if it could generate enough Cl even if I wanted to.

My SWG manufacturer recommends CYA at 60-80ppm, check your SWG owners manual
