Hi, I am a new member although I have been using TFP for years. Given the problem with CYA in the dichlorvos tablets, has anyone tried making a floating liquid chlorinator? I have been searching to no avail. I realize there are some safety (and efficacy) concerns but you would think in the 21st century we could design something that would keep your FC levels up for at least a few days without being a major safety issue. Anyone seen one or tried making one?
