| OK, I'll use a 3.5 ST to chlorine ratio in the future. So the dosage I normally use will treat 100 gallons of water with 2.9ppm chlorine, not the 3ppm I thought it would (I normally use a little extra anyway).
600ppm ST in a pond! In a 5000 gallon pond that would take over 11kg or 25lbs of ST. That's just a little bit more than the few grams we would normally add during a typical water change.
Thanks Roddy |
