Hey where are you in WI, I am in Green Bay.

Anyway now that the algae is likely under control you can drop the Chlorine levels back to 3-5 ish for normal use depending on the CYA level, but since it sounds like you have none 3-5 is good to shoot for right now. Was the "frog" a floater that you dropped sticks in to and it just floated in the water or what? I would start using them if you have them it will reduce the amount of liquid chlorine or bleach you have to add since it slowly dissolves releasing chlorine in to the water. It will also add stabilizer as it dissolves. Just keep checking the CL level for now.

You can probably by cya at Walmart, Lowe's or Home Depot. It may be called stabilizer or conditioner. Check the ingredients and make sure it says cyanuric or isocyanuric acid. Aim for an initial reading of 30. Put it in the skimmer and then don't retest, redose or backwash for about a week to let it dissolve. If it was me, I would just add the cya outright instead of messing with the frog floater. Until the cya starts dissolving, you'll need to test your chlorine morning and evening and each time add some bleach. After you start to get a reading, you'll be able to just test and dose with bleach in the evenings only.

I should have been clear. I would recommend using liquid chlorine or bleach regularly, but if you have the sticks and dispenser for the "frog" I would just use them up instead of tossing them or going to waste, then go back to liquid CL.
