About the pristine blue- stay away

It is an expensive system that adds copper to your water (you don’t want copper in your water) & claims you can run lower fc levels while also requiring you to use clarifier/floc (because the water gets cloudy due to low fc), enzymes (to combat the funk not eliminated by low fc levels), sequesterants (to compensate for all the copper), dichlor (which increases cya quickly & is very acidic) & “trade secret” mystery potions. While also selling you useless guess strips to “maintain” the charade.
All these things & problems they cause can be eliminated by just maintaining adequate & sanitary fc levels in relation to your cya.
