Thanks folks. I know they look just like yours but seeing we are a sharing bunch, I thought I would.
Oddly, the pool hasn't been vacuumed yet since taking the winter cover off. We were out of filter powder so just got the PH up to where it should be and smashed up some chlorine tabs and put them in the skimmer. Didn't have any Shock either. Then I brushed everything towards the bottom drain and turned the filter to pull from the bottom. It cleared up right away. It will be vacuumed today----ya know----grandkids want to come this weekend.
It's funny, dealing with pond water quality and pool water quality is soooo different yet the goal is to have clear water either way.
As for the volunteer, I knew a couple of summers ago but don't now. It seeds all over the place so am now sorry I let it go to seed back then. Yes, I liked them too. The leaves are real velvety and it's an impressive large plant.
