Hi, after ducks taking bath and being in the water for two days, I think it is good in one way that ducks are not doing into the Koi pond since it will increase PH if algae increase so quickly. Kois will get a shick. I have 210 watt UV lights in the pond but still it will be problems for PH increase since algae increase PH. This is the small pond and look what what only three ducks did with in two days. I just clean this on friday.

Male duck is molting.
Thiis before duck came to this house and the next photo is after changing this water on friday and today is sunday.

In one sense it is great that ducks are not going in to the big Koi pond since it will be a problem with PH imbalance. I donot know I can put a sump pump in and just water my lawn with it but it is shocking to look at this water from my eat-in-area.. Just want some friendly advise as per how to clarify this water? I did put algae cleaner which is fish and all bird safe but still it does not help.
