I know the TFP way is to use only the chems needed. But, do regular enzyme treatments like Orenda CV-600 do any harm? The argument for enzymes is that it breaks down non-living organics and oils taking the oxidation load off the chlorine, making it easier for FC to do the sanitation. I understand that you can boost chlorine levels to handle the extra load when needed. Just wondering is an enzyme product harmful to pool balance in any way? Or, just an unnecessary expense in the opinion of the TFP experts. I look forward to any comments.
