One of the most common problems we hear about when pond owners call in during the summer months has to do with water clarity.
Green or murky and cloudy water tend to show up as the pond warms up and the degree of coloration can vary from a light tinting to a full blown green or brown where you can’t see your fish any longer.
Many times a good filtration system will help a lot in smaller ponds with this type of problem because depending on the color, the issue could be an actual algae issue, or it could come from a lot of suspended material in the water. As long as the filter is adequate and the particules or algae cells are big enough, they’ll get filtered out in good order. The problem is, not every filter is equal to the task, and to make matters worse, some of these cells and particles are pretty darned small. Sometimes they’re so little that they can pass right through the filter without being taken out. And when this happens you won’t see much of a change in your water quality.
If you’ve watched several of our videos on dealing with green water algae, you know that one of the useful tools for dealing with the problem is uv or ultra violet light. This device emits light which radiates the algae that passes in front of it and this damaged the algae cells to the point where they either die off and/or become damaged and clump together in larger masses which ultimately leads to better filtering.
