Simply drain 1/2 the water from the catchment tank and let it fill back up in the next rain to dilute it.
Assuming you have 7500+ gallon tank, you won't be running out anytime soon anyway. Do the math on your roof size, subtract about 15% for "losses" and determine how many gallons you get for every 1" of rain. Mine gets 1400+ gallons with an inch of rainfall.
