Terrible Advice Tuesdays (T.A.Tues) The Ultimate RODI Unit Replacement?


Terrible advice Tuesdays: As long as you have a clean collection barrel, rain water is as good as RODI water.

The rest of the story…Rainwater can have any number of pollutants in it. Think about what might in the air in your city (industrial pollutants, car smog, etc) then add on what the rain water came in contact with as it was flowing to the collection barrel – bird droppings on the roof, metal gutters, etc,

Rain water is not as good as RODI water. If a fish store or someone told you to use rainwater in place of RODI water, run away…very fast
