someone put dishwashing detergent in my waterfall
someone put dishwashing detergent in my waterfall. What an absolute mess!!! I keep pumping the water out & replacing it but it keeps foaming. It is a 150 gallon, filled with rocks to the top & the water drops 3 feet to hit the basin filled with rocks. There are no fish in it.
Is there a home remedy I could use to remove the foaming action? I know there are products fro sale but I am looking for something I might be able to add myself.
