Those tabs are trichlor and are probably ok to use but we need to know the CYA level to be sure. You also need to be sure they don't have any unwanted things in them like copper. (Contrary to popular belief, it is copper that turns blonde hair green, not chlorine.) Check the label ingredients and let us know what it says. If you do use them, make sure your little ones don't play with the tablet floaters.
