Shock The Pool & Chlorine Tabs
I would like to know if it is safe to shock my pool while there are still chlorine tabs floating, or should I take the chlorine tabs out first? I don't want to mix the two if I shouldn't.
Your site is great and full of information!! Thank you
Thanks for the question and compliment Shelly
From a chemical point, there's no reason to take the tab floater out. Chlorine tabs are chlorine mixed with a stabilizer. From a shock point of view, you'll want to remove it because you'll want the shock to go to the pool as much as possible.
In fact, remove everything you can in the way of stairs, ladders, etc.. I was wondering why you were shocking the pool? Is it because you have an issue that calls for it, or is it for weekly maintenance? If your pool is perfectly balanced and it's just for weekly maintenance, I'd encourage you to test the combined chlorine (chloramines) first. When they're 0.6ppm or above is when you want to shock.
The weekly chlorine levels will kill the algae and bacteria. You can have this tested at your local pool store or use a Taylor FAS-DPD K-2006 pool test kit.
