No worries, I mentioned it as adding bubblers/fountains tends to be the go to solution for the well meaning but uniformed. I get why people do it, it seems logical. But it’s another example of why common sense is not always the right answer.

A much better solution (after reducing the nutrient input that is) is to increase the number of large aquatic plants (macrophytes). These take up the nutrients which suppresses the algae growth.
