Dick,
What would be the recommended daily water change? I've been hearing 5%, 10%, 15%, 20% etc. In your opinion for a 10000-12000 gallon pond. What percentage water change is acceptable? I'm looking at that 10% and then thinking to myself 1200 gallons, EVERYDAY for 30 days thats 36000 gallons a month....thats amounts to appox. four hundred dollars a month that means $4800 a year.....oh my.
