| Absolutely Lynn. Water for koi does not have to be spotless or like swimming pool water but if it is murky or green it dang well better be healthy and alive.
The real conversation is :
a) what is the difference between green water in a mud pond vs. a closed system barkyard pond? And what is the difference between green water in a closed and an semi-open system
b) as an extension of a), what is the danger of running a closed system like a mudpond or a semi open system. pH values being a huge outcome of murky or green water out of control. Too green, and your pH is at the ceiling and too cloudy white, and your pH is likely to crash through the floor.
IF, and only if , you understand the reasons behind what I just said should you attempt or allow water to be green or murky. Otherwise you are just lucky, until you're not. JR |
