Is it permissible to perform ablution with water from fish farm ponds?

If the water in fish farm ponds is clean, with no change in its color, taste, or odor, then it is pure and purifying, and ablution with it is permissible. If one of its characteristics changes due to fish excrement or something pure that usually accompanies it, it is still considered pure and purifying, and ablution with it is valid; because the change is due to a pure substance that accompanies it and cannot be avoided. However, if other water is available, it is preferable. As for water that mixes with a pure substance that usually separates from it and dominates one of its characteristics, the majority of scholars believe that purification with it is not permissible.
