I know most say to pour LC in front of a return with the pump on but I keep a solar cover on with a cutout for the spa spillover. Is it fine to pour the LC into the stream of the waterfall? It’s about 3’ deep there and seems like it would be mixed pretty well. A return jet is also about 2’ to the side of this. I’ve been doing it out of convince in the morning before sunrise/leaving for work.
