however it cannot produce water as quick as mine evaportates (five gallon a day.)
Not sure what system you have, a friend of mine just got a rainsoft system and it does her whole house, showers and all. I keep forgetting to take my TDS
meter over to her house to see what her output water uses.
The only filter I know of that uses potassium permangenate is an iron filter, I have one, as our well water has alot of iron in it, if the p. permangenate is not removed from the water completely I can see it causeing serious issues, as itis a powerful oxidizer, however, I would think the carbon filter would remove it. What kind of system did you buy that will only produce 5g per day??
