Ok, I googled it and found out what a skimmer sock is. I will order some of those and try that. Do you think it would be beneficial for me to shut the filter off overnight and see if the algae will settle to the bottom and then we can try to vacuum it to waste? Or should we continue to run our filter 24/7 until this is cleared up? Do you think I should add some borax also? I'm pretty sure my PH was low, 7.2 or so, before I started this super-cholorination process. Thanks for any advice you can give me.
